I have an iPod Touch (second generation) with iOS 3.1.2. Will I lose battery life or performance if I update to the latest iOS (4.2.1)?
These are the closest answers I could find:
- iOS 4.2 on iPod Touch 2d Gen: is it worth it?
- Does performance degrade between iOS 3.1 and 4.1 for the iPod Touch 2nd gen?
However, these relate to somewhat different versions of iOS.
