T-Mobile BlackBerry phones are GSM ONLY
Boost Mobile is iDEN and the new BlackBerry plans coming out are for CDMA Boost only.
A T-Mobile, Sprint, Verizon, AT&T or Nextel BlackBerry WILL NOT work for Boost. Sprint and Nextel COULD work if the billing system and activations for Boost Mobile were more open to accept outside phones, however it is not possible at this time. AT&T and T-Mobile are GSM, incompatible technology with iDEN and CDMA so they wont work at all, ever. Verizon is compatible with CDMA but Sprint does not have an open agreement for CDMA swaps.
