my sidekick just recently broke and theyre telling me there is nothing they can do for me.
ive been to so many stores and none of them would help me i even called customer support and after 7 times of hanging up on me they finally said to send in the phone and they would send me a new one...i waited and when i called back to ask about it they kept hanging up on me

my friend gave me his old at&t sync and said if i could unlock it to tmobile i could have it but i dont know the code...

cant anyone help me?
please?
