So, ive had a hard time with this but ive called booost mobile like 6 times, first they asked for the pin, so i had to contact the person i bought it from for the pin, when i got past that, they gave me an MSL number and PHone number. BUt they needed to programm the phone, But it was,nt working. Now someone told me i need to download something called "CDMA workshop" or something, to program the phone, but i have no idea how, and ive heard i can do it from the phone itself. so can anyone help me out? Its a used phone that has been flashed to boost mobile from sprint. phone called the epic 4G" EDIT: I recently downloaded CDMA WOrkshop, so, how do i use it to Programm the msl number and phone number? I think thats how your suppose to do it..
