iPhone 4

Apples iPhone 4
Apples new iPhone4 has addressed some performance issues prevalent with the iPhone 3G. The latest operating system iOS 4.2 can be installed on to the 3G but do not expect the same performance as the 3rd generation iPhone only has a quarter of the 512MB of RAM found in the new phone.
You also have to bear in mind that by running the iOS4 system on the 3G iPhone disables some of its features such as: background wallpapers, keyboard support, bluetooth, multitasking and a data protection feature.
