in the past couple of months i have been using an unlocked iphone with t-mobile. everything was working well until 2 days ago.

generally, an "E" is showing on the phone indicating EDGE. 2 days ago i started to notice that a small "o" is showing instead of the "E". when the "o" is showing the internet still works just really slow. i am guessing the "o" means GPRS?

the "E" comes back when i am not in my home area.

anyone got any ideas what is going on?

thanks!
