I have an Iphone 3gs version 4.2.1 and Itunes ver 10.4.1.10 . I just got this phone from my brother and i am trying to sync it to my computer. Whenever i plug the phone in it asks me what i would like to do, but I tunes wont recognize it. If i plug my old Ipod in it works fine. I tried calling apple but i am not going to pay them by the minute to help me. If anybody can give me some pointers, it would be much appreciated.
