I bought an unlocked iphone 3gs today running 3.1.2 5.11.07, the guy i bought it from did the "reset all settings" before giving it to me. It was on the apple logo for about 4 hours then it just kept resetting it self. I hooked it up and restored it with a custome firmware made by pwnage tools. I have tried to run blackra1n but it doesnt load the blackra1n app on to my iphone. I am lost and sad because i though that i would be able to us my iphone by now. Please help, and thanks!
