Hey guys,

after a week of research and raeding every thread out there and trying everything i still can't unlock my Iphone 3G 4.2.1 BB 06.15.00. So please help me on this one.

I jailbroken and updated my baseband to 06.15.00 through redsn0w_win_0.9.6b5. and then added the repo666.ultrasn0w.com repo and downloaded the ultrasn0w, everything went smoothly as i followed every step on the tutorials perfectly. but nothing happens, when i try to put a sim card (for ex. Vodafone or o2) it still says : Sim Locked... (i even tried to reboot several times, and turned off the 3g option)

Please help me

Thanks in advance

Hasso
