iPhone 3GS

Bloomberg has a story about how iPhone 3GS is still selling like hotcakes..

Dropping the price of iPhone 3GS to $0 (after carrier contract) was a very smart business move from Tim Cook. While as this bloomberg article points out iPhone 3GS may be 2 year old phone from a hardware perspective, it still runs their current mobile operating system - iOS 5. So while you may be able to hunt down another $0 Android smartphone deal, it is very likely that it won't be running the latest version of the Android OS
