my storm is currently unlocked. ive jl cmdr'ed it, factory reset.. upgraded/downgraded and the phone is still unlocked. if its unlocked through the code process, then your storm will be okay. cheers
okay thank you all! after upgrading, i bricked the phone while trying to flash service books for my carrier (accidentally deleted an important file) so it would not even boot. since, it has been re flashed and is running perfectly with MMS and everything.
