After spending 2.5 hours on the phone today with AT&T tech support, i just found out there is a known issue with some 4S phones (mine is 32GB) that have done the iOS 5.0.1 update. For the record, techsup removed and replaced the voice mail box, reset the password, and was getting ready remove/replace my data plan (made me a bit nervous as i have unlimited). In trying to get a team leader's approval for that task she learned of this bug.
The symptoms on the phone are no indicator red dot for vm messages, and no listings of recorded messages on the voice mail tab. It is no problem to listen to the messages (by either dialing 1 or my own number). You just have no way of knowing new messages are out there. If i try to change the password or greeting on the phone, it never connects to the network and eventually throws an error message. WIFI is turned off and data/roaming are on.
Until an iOS update is released that hopefully fixes this bug, the only solution is to check voicemail after every missed call. Quite a PITA. - mastman
