hi all,
i just bought a new iphone 3g with the os 3.1.3, i think it has the new bootrom so i dont know how to jailbreak it yet.
i read the below link but its said "for iPhone 3G and 3GS Users (New Bootroms): We strongly suggest that you stay away from this official upgrade until and unless the DevTeam or George Hotz releases new jailbreaking and unlocking tools for 3.1.3 firmware"
