What is it with this board and people trying to one up each other?
How does one turn off EDGE/3G while using WiFi? I didn't know it was possible. (I knew you could turn off 3G, but how do you disconnect from the EDGE network?)
I would call AT&T and have them reset your visual voicemail system. I've had this happen before and after they reset it, things worked like they were supposed to.
