so i saw on a thread someone saying they tried a verizon rom and got true hspa+ but no call or sms or something like that, i was wondering how dangerous is it to flash a verizon radio on the sprint one, i want to update to kit kat but i will be stuck on edge and that is something i can not deal with, im in the us using tmobile, so if you flash a verizon radio and it works cant you use it for flashing kit kat roms that are sense?
