I recently called T-mobile and unlocked the phone but i am with AT&T. Well everything is going smoothly ecxept one thing i can neither send nor recieve picture messages. I have searched on google like crazy to find a solution to this problem but the only thing i have learn is that i have to change my data settings from T-Mobile to AT&T. I called AT&T and they said they cant fix this problem because the phone is not associated with there company and they dont have the book on it. At this point i am very fustrated because i just want my phone fixed. Please help
