So I just bought a new white iPhone 3GS, running 3.1.3 stock already. After trying sn0wbreeze which worked easily on my 3.1.2 to upgrade and unlock, I was confused. I had also used sn0wbreeze to easily jailbreak 2 3G's in the past month. I just used Spirit, which is hands down the best jailbreak thus far. Even snappier than blackra1n (sorry, geohot). Can't wait to get OS 4.0 and jailbreak it. I wounder if any devs would just put up their ipsw?
