Press the home button twice.
If the iPad is running version iOS 4.2 or later then it will be able to multitask apps that have been designed to multitask.
Multitasking is available only with third-generation iPod touch (32GB and 64GB models from late 2009). However, only apps designed for iOS 4 will allow this feature.
iOS is not compatible with any iPod that is not an iPod touch. This means there is no way to install it on an iPod shuffle, classic, or nano.
iPod download iOS 4.3
You do not get iOS 4.0.2 when you update an iPod to iOS 4.1. iOS 4.0.2 is an earlier version and precedes iOS 4.1. The next version after iOS 4.1 will be iOS 4.2.
The 8gb iPod is not capable of downloading the IOS 4.3 update. If you want to run IOS 4.3 on your iPod, you will need to update to at least a 32gb iPod.
Only certain model iPod touches are capable of supporting iOS 4.3. The minimum iPod touch capable of supporting iOS 4.3 is an iPod touch 3rd generation, from 2009. The highest iOS that this model iPod touch supports is iOS 5.1.1.
Sadly, no. The latest version of iOS for the 4th Generation iPod Touch is iOS 6.1.5.
iOS 4.2.1 is the highest iOS firmware you can reach on the iPod Touch 2nd Generation.
There is no way to undo iOS 7 after restoring your iPod because iOS 7 is not released yet. However, to downgrade the iOS of your iPod simply download the firmware of the iOS you want from the Internet. While in iTunes, hold shift as you click "Restore my iPod to factory settings" and choose the file you just downloaded and your iPod should be on a lower iOS.
No it did not. It had IOS 6. But you can get IOS 7 on it. Also when IOS 7 came out they put it on the iPod 5 in stores.
No, only iPod Touch 5 can use iOs 7
