Yesterday first time I tried to send a photo through Itunes to my Iphone. When I tried to sync --> it is thinking for sometime and then it throwed me a message "unable to sync" or something like that.... From then I am not getting any rings when somebody called me. It became silent when somebody calls. Finally what I did is, I just turned on the vibration so that I am able to know that I am getting a call. Please let me know how to get the ring when somebody calls me.
