hi, well...my problem is i just recently bought an unlocked T-mobile hd2 to be used on At&t, it runs on edge as expected and i am fine with that, but when not on wifi the internet browsers and apps like youtube and facebook i get "Cannot Connect" messages telling me i have no connection to the internet, i do have a data plan on att but it is for the iphone, i was thinking maybe the reason for this is because the iphone data plan is somehow different then what this phone can recognize, but i am not for certain, if anyone else has had this happen to them or knows what the problem might be i would greatly appreciate some info, thanks
