Hey guys, this is for AT&T iPhoners or just AT&T people in general, i noticed that if i fall asleep on the phone with my girlfriend the call always ends at around 3 hours and 30 mins..all the time! I thought that since there wasnt anyone talking that the call just might automatically end when but today i was talking to her the whole time and the call just ended at around the same time! Is this "call time management" something i just dont know about?
