I want service with T-Mobile . Got an Unlocked Samsung Epix i907 because AT&T wouldn't approve my credit for a rate plan monthly(and wanted a 0 deposit!!), and I MUST have THIS phone all AT&T's pre-paid ones suck. . I'm worried I won;t get approved credit-wise but I have been a good customer of T-mobile for years in the past. Will T-mobile be able to give me a prepaid SIM card, not sure if their prepaid stuff have SIM's
