I'm getting alittle confused trying to search about these forums...i have a 3g phone jb/unlocked with yellowsn0w...i'm just curious if it's safe yet to update my fw, or will that lock me back up? i noticed yesterday my version of yellowsn0w updated, so i wasn't sure if that meant it was safe now....also i my phones been getting a bit buggy and i'd like to "rejailbreak" it, but how do i do that without updating to the new firmware?
