The update contains over 200 new features, including the following:
You can update it to iOS 5 the same way you update it to any other iOS version. The 4th generation (and indeed the 3rd generation) iPod Touch can be updated to iOS 5.
No
No you just update form iTunes
You cannot. If you buy a new iPod or iPad or iPhone, it comes in iOS 4.3.3 and you have a choice to update to IOS 5 or not.
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.
You cannot. The iOS 5 update is only for Iphone 4, iPod touch 4, iPad 1, iPad 2
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.
If it is running anything below iOS 5 you need a cord to update but if it is running iOS 5 or higher than you can update it using WI-Fi.
If it doesn't already come with it then go to iTunes and when your iPod comes up click "Check for Update" Then the proper update will download and install. If you already have iOS 5 and you want iOS 5.0.1 Then you can update directly from your iPod by going to Settings>General>Software Update to auto check for update.
Plug your iPod into the computer to charge it and it will ask if you want to update it.
it needs to be an ipod touch 3rd or 4th generation. just plug in with itunes and it will ask u if u want to update your software to ios 5
Sadly, no. The latest version of iOS for the 4th Generation iPod Touch is iOS 6.1.5.
