For some reason all this morning I have not been received an Edge or 3G data signal on my iPhone. I can still connect to my Wifi and browse and check e-mails but I can't do these if I tun off my Wifi connection. All of this was working fine last night, I don't know what happened since then. I can also make calls and send text whether I'm connected to Wifi or not. I've done some research but can't find anything. Is anyone else having these problems? Is it something on AT&Ts end? HELP!!
