I don't support this because Tmobile is a buisness and having a buisness you have to sell to make money. Plus you also don't need a sidekick anyways. Ok your deaf but you can use any other phone all of them have tty on them. I know this because I am a phone atic and buy about 8 to 10 phones a year, i can afford it and i am only seventeen. So i am sorry and not to be rude but Tmoibl will not lower their prie on the sidekick just because your deaf. SORRY!!!
