I've been having this problem for about 2 weeks now. First I was using Radio 1.50 on the AT&T network in South Jersey and out of the blue when the connection would go from 3g to edge I could no longer connect to the internet, receive emails or anything, voice was fine. When I would get back into 3g range everything would work again. So I upgraded to radio 1.54.07 and at first everything was fine no problems what so ever. But after 5 days this radio does the same thing, I cannot do browse the web or get my email if i go from 3g to edge but everything works fine once it is in 3g range. Anybody have similar problems or know how to fix them?
