So I bought my 3GS on launch day and for the past week or so I've been having some pretty obnoxious connection issues. My phone almost always displays full bars and a 3G connection, and yet I'm not getting incoming calls, outgoing calls fail, and when I try and surf on the 3G connection I get an error saying that the server is not responding. I restart the phone and it solves the problem . . . for a few minutes. The frustrating thing is that I can't tell if the phone is functioning properly until I try and use it myself; I'm more worried about the incoming calls and messages not getting through than being unable to make outgoing calls, although that is frustrating as well. I'm just wondering if anybody else in the city is having similar problems and it is an AT&T network issue or if I got a lemon and need to have it replaced (I'd rather not go through the headache of arranging a genius bar appointment in the city if I don't have to). Any help would be appreciated.
