Well I got a iPhone 3G (old bootrom) with 3.1.2 SHSH blobs (i am on 4.0 atm) my questions is quiet simples. I know i can go back to 3.1.2 and JB with PwnageTool or sn0wbreeze, however i would like to know if i should wait for the comex JB, well, I don't care for the hard work of having to downgrade, all i care is about it must be bugs free and stuff like that. Between PwnageTool or sn0wbreeze, which one is better? are them bugged? will i get any sort or problem? Thanks in advance.
