The Dev Team has updated Ultrasn0w to work with iOS 4.3.1 but keep in mind that they did NOT add support for newer basebands; they simply implemented 4.3.1 support!
Supported basebands:
iPhone 4: 01.59.00
iPhone 3GS: 04.26.08; 05.11.07; 05.12.01; 05.13.04 & 06.15.00
Steps:
1. Check your baseband to see if you can even unlock (go to settings, general, about and scroll down and look at your Modem Firmware)
2. If your baseband is supported then continue, if not then subscribe and check back frequently (I’ll have a video on it as soon as it’s updated to support your baseband)
3. Go inside of Cydia and check for the Ultrasn0w repo, if it’s not there then add it:
4. Open the repo and install Ultrasn0w
5. Enjoy your newly unlocked iPhone!
Thanks for watching and please subscribe if it helped!
