Iphone 2G jailbreak problem.
I have a 3gs which I JB with blackra1n with no hassles. I bought my little brother a second hand 2G iphone which had been jailbroken/unlocked before although im not entirely sure which program was used.
When I got the phone from (ebay) I have the usb connected to itunes screen on the phone when I turned it on and it will not go away. The seller is not responding and im not sure what I can do. I tried connecting to itunes but I get the message 'this phone does not have a compatible sim card inserted..bla bla bla'
So I thought Ineeded to rejailbreak it and unlock it.. So I tried running blackra1n but it just gets stuck on the 'running' screen..
The iphone will reboot shows the apple logo but geohots pic doesnt show up and the iphone screen goes back to 'usb connected to itunes'..
Im unsure what the best course if action is to take here..
Any help would be greatly appreciated.
