Can an iTouch 3G be updated to 6.0.1 ?
No, unfortunately iPod touch (3rd generation) is compatible up to iOS 5.1.1 only. iOS 6.0-6.0.2 is compatible with iPod touch (4th generation), iPod touch (5th generation), iPhone 4, iPhone 4S, iPhone 5, iPad 2, iPad (3rd generation), iPad (4th generation), and iPad mini.
No, Due to the older software. 6.0.1 is only enhancing the features.
The third generation iDevice cannot be updated to the latest iOS. The only devices that can be updated to 6.0.1 are the iPhone 5 and the iPad mini.
The iPod 4 & iPad 1/2 have IOS 6.0.1But the iPod 5 & iPad 3 & mini & iPhone 5 have 6.0.2.
