I Phone Unlock

1.Ensure you have upgraded to iPhone OS 3.0
2.Jailbreak your iPhone 3G using redsn0w or PwnageTool (this will also install Cydia/Icy)
3.Run Cydia or Icy
4.Please add the repo repo666.ultrasn0w.com to Cydia or Icy.  That last “o” is actually the number zero “0”! If you use the letter “o” you’ll get an error.

6.Reboot your iPhone 3G
