iPhone Dev Team announced the release of Ultrasn0w for iPhone 4 on their blog:

  • iPhone4 baseband 01.59
  • 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04

So if you have jailbroken your iPhone 4 on iOS 4 or iOS 4.0.1 usingJailbreakMe then you should be able to install Ultrasn0w from Cydia to unlock your iPhone 4 for free.

Ultrasn0w 1.0-1 can also be installed by iPhone 3G and iPhone 3GSusers to unlock their iPhone on iOS 4 or iOS 4.0.1 or earlier (upto iPhone OS 3.0).

Here are the steps that you can follow:

  1. Launch Cydia
  2. Please add the repo repo666.ultrasn0w.com to Cydia.  That last “o” is actually the number zero “0”. If you use the letter “o” you’ll get an error.
  3. Then search for ‘ultrasn0w’ in Cydia and install ultrasn0w.
  4. T-Mobile USA users should disable 3G before using ultrasn0w.

This should successfully unlock your iPhone.

We have already got confirmations from our readers that they’ve successfully unlocked their iPhone 4.

As always, let us know how it goes.
