How will it work jailbreaking an iphone 4 thats jailbroken with jailbreakme as that was the only jailbreak available and it wont allow you to load a custom firmware onto it? People that jailbroke with spirit or jailbreak me on 3g/3gs have to downgrade to a 3.1.3/2 firmware dont they to use the new snowbreeze but that isnt possible on an iphone 4.
