UltraSn0w iPhone Unlock for iOS 4.3.3 Released

By , May 6, 2011

Just about 2 weeks after releasing the previous version, the Dev Team released today UltraSn0w 1.2.3, a software unlock for iPhone 4 and iPhone 3GS. Like its predecessor, this newer version of UltraSn0w doesn’t unlock the latest basebands.

UltraSn0w will only work for the older iPhone 4 baseband 1.59.00, and iPhone 3G/3GS basebands 4.26.08, 5.11.07, 5.12.01, 5.13.04, and 6.15.00

Again, just to be very clear, if your baseband is different from any of the basebands listed above, you will not be able to use UltraSn0w to unlock your iPhone.

As usual, UltraSn0w can be downloaded from Cydia. Make sure you reboot your iPhone after installing UltraSn0w.

    i have ios 4.3.3 jailbroke, with now 6.15fw I tried ultrasn0w but it still wont let me use the internet without wifi. any ideas

    Just an update guys. If you are on a Jailbroken iPhone, with a baseband in the list of basebands thats ultasn0w works with, it doesn’t means tat you will be able to unlock the phone after you JB 4.3.3 with Redsn0w. That’s because Redsn0w will not preserve your firmware and when you update your iOS to 4.3.3 using iTunes your firmware will have changed to 5.16.*.* which cannot be unlocked as yet using Ultrasn0w.

    Its not a pain if you use AT&T and dont need your carrier unlocked. But will affect you if you wanna use other service providers.
