Never experienced it before the upgrade so it is possible my problem is also associated with the upgrade. Until I read this I assumed it was a problem with AT&amp;T, and while it could still be their problem, it sounds like there is another possible reason.&nbsp;</p>

Had that before the last update. Everything looked fine, but didn't get calls, and nothing happened when I dialed. Usually discovered when dialed using BT in car. Dialing worked but I wouldn't hear the dial tone, etc. when I hit the dial icon. Shut off and turn back on and things wuld be fine, and often it would then pick up the voice mails. Like I said though, last update (3.1.2?) seems to have fixed it.

I have had this issue too, before and after the update. It is usually in the same geographic location and my other ATT phone is getting 4 bars opf signal in the same place.

the old 3.1.0 had this problem if theres no service for a period of time, no problem with 3.1.2
