Saying Goodbye

30 10 2014

If it’s time to say Goodbye to one of your Apple devices because you are impressed by an innovative new model and cannot wait to order, here is what you should know and what you should do with your old device if you plan to sell it.

20140731-081720-29840253.jpg

In my example I talk about an iPhone 5 running on iOS 7 and temporarily used by my wife. This version of Apple’s mobile operating system turns ‘Find my iPhone’ and ‘Activation Lock’ automatically on. Additionally the Apple ID is secured with 2-Step-Verification.

Activation Lock
Loosing a device with sensitive data may compromise your identity in the digital world followed by severe problems with law. At WWDC 2013, Apple unveiled Activation Lock, a new feature in iOS 7 that locks stolen phones even after thieves wipe them.
Apple’s Craig Federighi
“We think this is going to be a really powerful theft deterrent.”
The company on its website
“Losing your iPhone feels lousy. Thankfully, Find My iPhone can help you get it back. But if it looks like that’s not going to happen, new security features in iOS 7 make it harder for anyone who’s not you to use or sell your device. Now turning off Find My iPhone or erasing your device requires your Apple ID and password. Find My iPhone can also continue to display a custom message, even after your device is erased. And your Apple ID and password are required before anyone can reactivate it. Which means your iPhone is still your iPhone. No matter where it is.”

If activated, 2-Step-Verification needs a SMS capable device. Every time you want to have access to your Apple account you need a verification code Apple will send to one of your trusted device. So, selling a device should always be followed by removing the device from the list of trusted devices. But don’t worry, if you didn’t go the recommended way you can manually remove a device from this list.

Your Apple account …

Apple’s mobile devices are connected with the Apple ID you used during setup. If you go to your support profile you will see all devices connected to this ID.

20140731-081813-29893625.jpg

Sold devices or devices you do not own any longer (giveaway or theft) must be removed from your account to avoid abuse.

Backup your device …

If you want to purchase a new iPhone or iPad backup your old device to iCloud (and/or iTunes) to use this backup for configuring to predecessor. Keep in mind that account and other personal data are only included in an iOS backup if you use an Unlock Key on your device. If you later run through the setup process of your new device you can restore the backup from iCloud and there is nothing more to do.

You can use an iOS backup of an iPhone to configure an iPad and vice versa.

The only thing you have to do is to install apps that are designed for just one of the two devices.

Two cases …

Distinguish between these two cases:

If you still have access to your iOS device …

Follow these steps to protect your data and get your device to its factory default state for the new owner:

Go to Settings – General – Reset, then tap
Erase All Content and Settings.
This will completely erase your device and turn off iCloud, iMessage, FaceTime, Game Center, and other services.
If you’re using iOS 7 and have Find My iPhone turned on, your Apple ID and password will be required. After you provide your password, the device will be erased and removed from your account so that the next owner can activate it. If you don’t remove you device from your account, Activation Lock will prevent other users to activate the device.

When the device is turned on for the first time by the new owner, Setup Assistant will guide them through the setup process.

Important …

Do not manually delete contacts, calendars, reminders, documents, photo streams, or any other iCloud data while signed in to your iCloud account.

The content would also be deleted from the iCloud servers and all of your other iCloud devices.

20140731-081914-29954047.jpg

Apple will send you an E-Mail which confirms that you erased your device and that it’s removed from your device list and the list of trusted devices defined for an account with 2-Step-Verification. You now can say Goodbye and sell it or shed love and give it to your wife or your child.

If you no longer have access to your iOS device …

If you didn’t follow the steps above before selling or giving away your iOS device:

Ask the new owner to erase all content and settings as described above.
If you’re using iCloud and Find My iPhone on the device, you can erase the device remotely and remove it from your account by signing in to icloud.com/find, selecting the device, and clicking Erase.

Erasing a device remotely is only possible if it’s still connected to the internet (via cellular network or WiFi and turned on). If this is not the case then the device will be erased when it connects to the internet again.

When the device has been erased, click Remove from Account.

If you’re unable to complete either of the above steps, you should change your Apple ID password. Changing your password won’t remove any personal information that is cached on the device, but it will make sure that the new owner can’t delete your information from iCloud.

I removed the SIM card from the iPhone to simulate a SIM, deactivated by the carrier and turned the phone off. On my iPhone 4S I opened ‘Find my iPhone’, signed in with the Apple ID used on the iPhone 5 and started the process of erasing the device.

20140731-082013-30013251.jpg

Because the iPhone 5 was turned off, it couldn’t receive anything and so ‘Erase’ couldn’t be executed. After turning the device on it connected to the internet via my WLAN which basically simulates the insert of a new SIM card with which the device can connect to the internet via cellular connection.

20140731-082058-30058102.jpg

It’s over now.

20140731-082135-30095942.jpg

A new liaison is waiting. What should be said is that the whole procedure is incapable for being used in human relations.

Troubleshooting …

After erasing the iPhone and removing it from the account via the app ‘Find my iPhone’ something went wrong. The device couldn’t be activated any longer. The iOS setup procedure stopped with the message ‘… activation server temporarily unavailable …’. Several further attempts to activate the device weren’t successful.

20140801-181743-65863625.jpg

It turned out that there is just one way to fix the problem, doing a RECOVERY. It needs a computer with an installation of the latest version of iTunes. There is no need to do more than just a recovery. Follow these steps to make your device ready for a new activation:

  • Turn off your device.
    If you can’t turn it off, press and hold the Sleep/Wake and Home buttons at the same time and wait a few seconds for it to turn off.
  • Plug the device’s USB cable into your computer only.
  • Hold down the device’s Home button as you connect the USB cable to it.
  • When you see the ‘Connect to iTunes’ screen, release the Home button.
  • Follow the instructions in iTunes after clicking on ‘Recover’.

Summary …

This concept map (created with the app INSPIRATION for the iPad) summarizes the steps to sell an iOS device.

20140803-210815-76095142.jpg

If you have to say Goodbye, do not cry. I’m quite sure that each iteration of an iOS device and the operating system will let you forget your former darling in a jiffy.

iOS Compass

20 10 2014

You iPhone comes with the built-in app Compass which includes a Bubble Level designed by Jonathan Ive.

Open the app, swipe left, and move your device around a horizontal or vertical axis to see whether something is thrown out of kilter.

Unfortunately the Compass app won’t help if you stray from the straight and narrow or an Android fanboy went astray.

20140729-152858-55738394.jpg

Compass is a nifty little helper and saves about 1$ for picking up a bubble level app from the App Store.

Apple’s app wouldn’t work without the help of the nature, particularly the Earth’s magnetic field. It’s mostly caused by electric currents in the liquid outer core, which is composed of conductive, molten iron. Loops of currents in the constantly moving, liquid iron create magnetic fields.

From afar, the Earth looks like a big magnet with a north and south pole like any other magnet (the pole located up in northern Canada is really the magnetic South Pole).

The technique …

If you are a proud owner of an iPhone you have purchased a device which is in someway much more sensitive than any human being ever can be. iPhone’s sensors know all about your finger, the distance between your ear and the device, the brightness of the environment, the strength of the magnetic field you are actually in, and your current location and movements.

This mind map shows you all sensors implemented in the new iPhone 5S.

Feel free to download this map from my Box account.

The alternative file formats have been created with iThoughts for iOS (.ITMZ file format). Compatibility to other tools is limited. The DOCX file format is suggested for those who don’t use a mind mapping tool. The file contains the image as well as a detailed outline of all topics.

With the iPhone 4 Apple manifested it’s market leading smartphone technology. The integration of the 3-axis accelerometer, the gyroscope, and the Hall-Effect-based compass provides full nine degree-of-freedom (9DoF) motion sensing and can be seen as a milestone in the evolution of portable consumer electronics devices.

Hall-Effect
A voltage difference (the Hall voltage) is generated across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current (discovered by US physicist Edwin Hall in 1879). The voltage measures the magnet field’s intensity.

9DoF
The position of a rigid body in space is defined by three components of translation and three components of rotation, which means that it has six degrees of freedom.
Translation: Moving up and down, left and right, forward and backward
Rotation: Tilting forward and backward, swiveling left and right, pivoting side to side
iPhone’s sensors provide 9 independent parameters and so we talk about 9DoF: 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer

The Compass app uses some of the 10 sensors of your device to process their raw data and display them as a user-friendly information.

20140729-111423-40463919.jpg

The Attitude (rotation) sensor provides the pitch, roll and yaw (azimuth) angles of the device relative to the normal horizon. It’s part of the Device-Motion information computed by the iPhone operating system from the main sensors, particularly the gyroscope.

Although the gyroscope provides precise measurements of the angular rates, calculating rotations only from the gyroscope are subject to a noticeable drift due to various inherent physical phenomena like gyro precession. The Device-Motion computation automatically uses measurements from the accelerometer to minimize the drift.

There is much work for iOS to show precise data because the Earth’s magnetic field wasn’t designed by Apple saying NO to complicated things.

Strength and direction of the magnetic field is dependent of your current position.

  • Intensity
    is the overall strength of the magnetic field.
    This globe shows the intensity and direction of the earth’s magnetic field at the surface of the earth. On average, the field strength is about half a gauss; 0.5 gauss or 50 μT. Locally, however, this varies. For example, the field strength in Cupertino, USA is about twice as strong as in Rio de Janeiro, Brazil.
  • Declination
    is how far off from true north you would expect a compass to point, where true north points straight to the earth’s north pole (the top of the globe, where it rotates).
  • Inclination
    is how much the field direction is pointing up (into the sky) or down (into the ground). Up is denoted as positive numbers, while down is negative.

The app …

The Compass app has gone through a major redesign with Apple’s release of iOS 7 in October 2013. Redone from top to bottom, it now looks like a cockpit flight instrument with no hint of wood paneling or rosy parchment paper of older versions of iOS.

The compass offers all of the features present in the iOS 6 version of the app (though the choice between true north and magnetic north has moved to Settings – Compass), and as an added bonus it refers to geolocation services when showing your current city and state, and latitude and longitude coordinates below. In addition, if you want to follow a particular bearing (say, 23 degrees northwest), you can tap the compass face once to set it; as you move around, the compass draws a red arc on the inside of the circle, showing how far you’re deviating from your original course.

20140729-074115-27675992.jpg

Finally, the new compass recalibration tool says farewell to awkward figure eights and waving your phone in the air; instead, you play a make-the-dot-follow-the-circle game that’s not only much more enjoyable, but easier to explain to random passersby.

That may be all for the compass tool, but it’s not all the app has to offer:
Swipe left on the compass, and you access an iOS 7- exclusive tool: a horizontal and vertical level. The level is wonderfully simple, using white, black, and green geometric shapes to display level information.

Place your device flat on its back, and two overlapping white circles appear with a degree of measurement in the center; as you adjust the level, the circles change until they overlap perfectly for more than a few seconds—at that point, the screen goes bright green to indicate you’ve achieved a perfect level. Hold your device in landscape or portrait mode in an upright position and the app shows a rectangular level, dividing the screen into white and black squares. When the white square reaches equilibrium with the black square, the screen turns green. The y- and z-axis then are parallel to the ground and the x-axis is perpendicular to the Earth’s surface.

Limitations …

If you find yourself having problems with the motion sensors that power your iPhone’s Compass, Maps, or other third-party apps, you need to calibrate the compass before using Maps, Compass, or other apps that use this feature.

The calibration screen that appears when you first launch the app hooks into Apple’s entire Core Motion framework, which includes your accelerometer, gyroscope, and other motion data. Calibrate the device in Compass, and it should properly adjust your motion data in other apps. Unfortunately, this calibration isn’t perfect.

You can try to fix badly-behaving motion data by force-quitting and relaunching Compass to trigger the calibration screen. The accuracy of digital compass headings can be affected by magnetic or other environmental interference, including interference caused by proximity to the magnets contained in the iPhone earbuds or your car’s dashboard. You’ll have the best luck if you calibrate at least several feet away from any other magnetic or electronic devices.

Apple does note in the support document TS 2767 that

you shouldn’t rely on it to determine precise locations, proximity, distance, or directions.

Sensors such as the one in the iPhone aren’t necessarily as good as a traditional mechanical compass, sadly.

Summary …

A nice-to-have little app showing us what miniaturized sensors in modern devices can do for us in a pretty precise way.

Messing with powerful magnets near your iPhone can alter the calibration of the sensor. While the compass can re-calibrate itself, it is possible to mess it up. There are a number of stainless steel shields inside an iPhone that might have been very slightly magnetized by passing magnets. While the compass may work reasonably well, it doesn’t show the same overall field strength when you twist the device around in different directions. Avoid getting powerful magnets too close to your iPhone.

The North and South magnetic poles wander widely, but sufficiently slowly for ordinary compasses to remain useful for navigation. However, at irregular intervals averaging several hundred thousand years, the Earth’s field reverses and the North and South Magnetic Poles relatively abruptly switch places.

But don’t worry. If this happens Apple will immediately release an update to iOS which lets you find the way back home.

About the iPad

8 10 2014

People once marveled at the interactive tablets carried around by characters in Gene Roddenberry’s Star Trek, or the touch screens in Spielberg’s Minority Report – dream futures that have become reality.
In 1983 Apple co-founder Steve Jobs stated that his ultimate ambition was

“to put an incredibly great computer in a book that you can carry around with you and learn how to use in 20 minutes…”.

That vision would take him 27 years to realize. With the launch of the iPad in 2010 Apple’s engineers again demonstrated their formidable skills.

A disruptive innovation is an innovation that helps create a new market and value network, and eventually disrupts an existing market and value network (over a few years or decades), displacing an earlier technology.

Within a few years the early idea of Steve Jobs hit the computer industry to the core and the list of MUST-HAVE-Devices was complemented by a tablet and analysts started talking about the Post-PC-Era.

20140721-063722-23842489.jpg

With the release of the iPad, mobile devices reached a new quality because of it’s screen size and the possibility to operate them just with the fingers, without any peripherals. They initiated a shift in paradigm of teaching and learning as well and from that time ‘people could hold the internet in their hands‘.

20140721-092919-34159876.jpg

Historically the term first originated when Apple‘s founder Steve Jobs discussed the future of personal computing during an interview alongside Bill Gates at the fifth All Things Digital conference in 2007. At that time he described

“a category of devices that aren’t as general purpose, that are really more focused on specific functions, whether they’re phones or iPods or Zunes or what have you. And I think that category of devices is going to continue to be very innovative and we’re going to see lots of them,”

Jobs said.

20140721-095054-35454443.jpg

Apple’s been kicking around the idea of a tablet since at least 1983. From real, physical prototypes to out-there ideas such as the Knowledge Navigator – the company has, somewhat unsurprisingly, seen fit to investigate the possibility for almost as long as it’s been around. For one reason or another, though, they’ve never actually produced a device which saw the light of retail day (besides the Newton). Perhaps that’s part of the fascination that Apple fans have with the product a it’s been rumored so long, and seemed on the verge of actual arrival so many times that it’s become a Holy Grail of sorts for the tech community.

Optimizing the workflow …

On the go, in the air, simply everywhere an iPad may help to optimize workflows in all areas of our lives. Apple published tons of information about the application of it’s jack-of-all-trades. You can find some interesting documents when you open the iBooks app and search for ‘ipad at work’.

20140721-063829-23909076.jpg

In 2011 the Federal Aviation Administration approved the iPad for in-cockpit use and many airlines, starting with Alaska Airlines, began to optimize their pilots workflow.

20140721-091355-33235477.jpg

At United for example, the iPad became standard equipment on the flight deck, providing pilots with one-touch access to charts, maps, and other crucial navigation tools.

In a business where extra weight translates directly into extra costs, choosing iPad means fewer pounds on every route United flies—not to mention less baggage for United pilots to lug through the airport.

“A pilot’s flight bag weighs about 45 pounds,” says Captain David Sambrano, who has flown United planes for 22 years. “With iPad, we get rid of that big 45-pound bag. Being able to take all those books and charts and bring it down to about a pound and a half is incredible.”

Eliminating all that paper translates into serious savings, says Captain Joe Burns, Managing Director of Technology and Flight Test, another 20-year United veteran. “With iPad we’re able to save 16 million sheets of paper a year. Just removing the weight of that paper works out to 326,000 gallons of fuel saved per year.”

But replacing traditional flight charts with electronic documents on iPad does more than merely lighten the load. It also helps United pilots pinpoint essential flight information the moment they need it.

“In the past we’d have to pull a binder out, find the airport and the approach code, pull the paper out, clip it onto a chart holder somewhere, then enter that data into the flight control computer on the aircraft,” Burns recalls. “We view iPad as a big safety and time saver.”

“The iPad display allows us to see the chart very clearly,” Sambrano adds, “and it’s readable in different types of lighting, which is extremely important. And you can get to that particular chart or that particular piece of information so quickly.”

iPad in education …

The iPad can be a transformative tool in education as it can house all resources (books, readings, video, audio), connects to the internet for doing research, provides a vehicle for maintaining communication, replaces ‘dead tree’ paper versions of resources and does it all in an easy to carry around, quick starting, and simple interface.

20140721-070831-25711364.jpg

Using an iPad in classrooms is a paradigm shift from didactic models of ‘Teaching’ to constructivist models of ‘Learning’. Technology has always been good that and that’s one reason schools began investing in computers in the 70s and 80s. But the iPad brought that engagement to a very personal level.

It’s because a touchscreen is much nearer to human activities than any other device or textbook could be.

What we do is mostly what we do with our hands. It’s our first approach to new things.

Creating artworks, modeling new devices or writing down all the ideas leading to the E=m c c equation on a sheet of paper while walking through the room and reflecting our thoughts is almost always done by hand.

Apple-IBM …

In July 2014 Apple published a press info about

Apple and IBM Forge Global Partnership to Transform Enterprise Mobility

What does this mean?

IT departments and tech purchasers will now enjoy

  • the reliability of IBM’s enterprise solutions on Apple’s platform
  • powerful mobile device management
  • tailored services and support
  • the most secure mobile operating system
  • easy to use devices with lots of new tailored business applications
  • an incredible lifetime cycle because of high build-quality and less fragmentation of the OS

Apple’s devices were already in use in many enterprises but now the footprint is institutionalized.

Some tidbits …

Call it innovation, evolution, improvement or whatever you like, the first iPad is quite different from the actual model, the iPad Air, if you take a look at the details.

1st Gen iPad Air
Power 25 Wh 32 Wh
Memory 256 MB 1000 MB
Display 132 ppi 264 ppi
Weight 730 g 478 g
Storage 16,32,64 16,32,64,128

The most impressive developments of Apple’s engineers are the Retina display and the 64-Bit-Processor which opens the door to high-performance software applications.

20140721-063917-23957966.jpg

Build-quality, performance, and the operating system show us what Steve Jobs had in mind when saying “to put an incredibly great computer in a book that you can carry around with you and learn how to use in 20 minutes.”

Summary …

A shining example for disruptive technology developed by a company with a strong focus on high-quality products serving people and enriching their lives.
