This new 32GB Apple iPhone black (AT&T) 3GS mobile from Apple is really a good model.It is a faster version than the previous phones.The battery life is really promising and it has a great multimedia quality. There are also other features of a common phone. How ever there is no facility for Multi-tasking and USB transfer. The 3Gs quality is not so great. The 3G has real good speed when compared to the previous phones.
