I have been trying to jailbreak my iphone 3gs with pwnage or blackra1n on mac and pc. When it gets to the point to reboot it will not with blackra1n and with pwnage it will go through the whole process then when it goes to reboot it comes back in recovery mode. Will not even come out of recovery mode no matter what I try. It is an apple iphone 3gs factory unlocked with 3.2.1 firmware. HELP!!!!!
