Thanks... I dont know what the hell is going on now! Edge is back, but now I cant make calls and if I DO happen to get one through, I can only talk for about 2 minutes before it disconnects. I reseated my sim card, and even restored the phone with no success. I just took the sim card out and put it in another phone, and still couldnt make calls. So... Im thinking now its either a flaky sim, or ATT's network is hosed up.
*Edit* Ok... wtf? I just went to ATT's site to see if anything is going on, and when I tried to log in, I got this: "The server you are attempting to contact is temporarily unavailable. Please try again later. We apologize for the inconvenience." Dammit... how annoying!
