Technical - Updating your iOS

Thought of sharing the experiance of updating iOS on apple device.

I updated my iPod Touch to 4.2.1 from iOS 2.1.2. Its very easy, steps/tips/tricks as below. I performed all these things on my Windows machine.

1.0 Connect your iPod touch to the machine and launch your iTunes.

2.0 Go to your device i.e. iPod touch and verify all the details viz device name, serial number, firmware version i.e. iOS version etc.

3.0 You can see the update and restore two options in the device menu.

4.0 Click on update.

5.0 iTunes will connect to app store and determine the latest version of iOS compatible for your hardware.

Note :- While updating, latest version available in market is iOS 5 but my hardware was not compatible with this, so smart app store determined to install iOS 4 on my iPod touch :).

6.0 iTunes will start to download the setup under iTunes store section in download tab.

7.0 This download should take around 3 hours of time. [ mine took 3 hours ]

8.0 This setup doesnt get stored at any location and as soon as download completes, it will start applying these files to your devices.

9.0 In the process of installation of iOS, iTunes will show two messages.

One as pop-up window - "Back-up iPod name>> "

And other

Processing software files....in the iTunes upper tab.

10.0 In whole process, i never saw a message as "Updating your iPod touch" its always shown as Restoring your iPod...not sure why this was.

11.0 Once the application of files is done, message of iPod touch being restarted is shown.

12.0 Your iPod touch is restarted and you are done with updating.

Key to successful updation is be patient , most of the time you will think nothing is happening but its not the fact.

Keep your iPod touch pluged in and you can see the new Version of iOS installed.

This is the best , what i can recollect. Please correct if i am incorrect at any of the steps.

Best Regards,
