UltraSn0w, the soft unlock for the iphone 3G 3.0 firmware is now available thanks to the good work of the Dev Team. This also works for 3GS now.

You have to jailbreak your iPhone 3G before you install UltraSn0w. To jailbreak your iPhone 3G, check out my other post.

  1. Launch Cydia.
  2. Add the following source to Cydia (note there is a “0″ in sn0w, not an “o”).
  3. After installing this source in Cydia, search for “ultraSn0w”.
  4. Install UltraSn0w and reboot your iPhone.

Note that T-Mobile users should disable 3G before using UltraSn0w.
