Edge no longer working

For the last couple of days my iPhone has not been able to connect to the Edge network. I have not yet called Apple for troubleshooting, but I thought I would come here and see if anyone has any input. Keep in mind I have attempted to use Edge both with full bars and with only a couple bars.

Thanks for any suggestions/answers!

trying turnign the phone off and on. I had this happen where, and that worked for me. Only happened once so far.

You can try turning on airplane mode, waiting a few minutes, then turning off airplane mode, too. I think that may force it to reconnect or something...

Reset it and try again. If that doesn't work, I'd also give ATT a try because it's their network. Maybe it's down temporarily in your area or something.

Turning the phone off and then back on fixed it.
