I have a boost phone but its really slow so I found a blackberry curve really cheap. i called them about 20 minutes ago they said blackberry probably won't work it would have to be a motorolla. they also gave me a list of phones that are compatiable and most of them are motorola's like I465, I335, I290, I58, I80s, I85s, I88s, I930, I925, I35x, I58sr, w385 and c290. most of the model numbers they gave me all start with an i. hope this helps
