List of Unlockable iPhone Basebands Supported by Ultrasn0w

At the moment, there is NO software-based unlocking for iPhone 4 and iPhone 3GS running on higher basebands such as 02.10.04, 3.10.01, and 04.10.01. Meaning, you will not be able to unlock iPhone 4 or iPhone 3GS running on these unsupported basebands. In your case, I would recommend you to check the baseband version of your iPhone. If you have 3.10.01 baseband installed on your device then there’s no software unlock solution for you. You can check some of the supported and unsupported iPhone basebands below:

Supported iPhone 4 / 3GS / 3G Basebands:

  • 04.26.08
  • 05.11.07
  • 05.12.01
  • 05.13.04
  • 01.59.00
  • 06.15.00
  • 05.14.02 via 06.15.00
  • 05.15.04 via 06.15.00
  • 05.16.01 via 06.15.00
  • 05.16.02 via 06.15.00

Unsupported Basebands:

  • 05.14.02
  • 05.15.04
  • 05.16.01
  • 05.16.02
  • 02.10.04
  • 03.10.01
  • 04.10.01

Alternatively, these Ultrasn0w unsupported basebands can be unlock using the SIM unlocking tool like Gevey SIM and Rebel SIM – a hardware unlock that works on all iPhone Firmware and basebands.

On the other hand, iPhone 3GS users with baseband 05.14.02 / 05.15.04 / 05.16.01 / 05.16.02 will be able to unlock their iPhone by updating its baseband to iPad’s 06.15.00 baseband
