I have a Tmobile blackberry curve 8320 that I just had unlocked and now I'm using it on ATT. Everything works fine except that I don't get my email pushed to the phone. I can send emails out but I don't get them in. I used this phone with Tmobile and everything was fine. When I go to set up email accounts, it asks me for username and password. I don't remember either of them. Please help. The Tmobile is not willing to help because I'm no longer their customer and ATT can't figure out what's wrong.
Perhaps not. I signed up for an unlimited data plan for an additional $15/month. I may not have indicated a change from my previous phone before doing so. Would a failure to do so result in the problem that I am having?
If so, is correcting the problem as simple as making a phone call? Is what I am looking for precisely the plan you mention - "a blackberry data plan"?
