UltraSn0w 1.2.1 released: supports iPhone iOS 4.3.1





ultrasn0w-121

The iPhone Dev-Team released an update to UltraSn0w that makes it compatible with iOS 4.3.1 for basebands previously unlocked. You can use ultrasn0w if you need carrier unlock and you have compatible baseband, preserved with pwnagetool, sn0wbreeze or tinyumbrella.

Ultrasn0w 1.2.1 supports only the following basebands:

  • iPhone 4: 01.59.00
  • iPhone 3G/3GS: 04.26.08, 05.11.07, 05.12.01, 05.13.04, 06.15.00.

You can install ultrasn0w via Cydia.

Here are DevTeam comments:

The iPhone Dev-Team has announced an update to UltraSn0w that makes it compatible with iOS 4.3.1 for basebands previously unlocked.

We’ve pushed out the 4.3.1 compatibility fix for ultrasn0w in Cydia — it’s now at version 1.2.1. If you’re not already at 4.3.1 and you need the unlock, please be sure you understand how to get to 4.3.1 using a custom IPSW that doesn’t update your baseband. There are lots of guides for this (like at iClarified.com).

This isn’t a new unlock! It’s to allow those who are already unlocked to use FW 4.3.1. It also fixes the signal bar issue for those who aren’t using the unlock but retain an older baseband intentionally.

After installing UltraSn0w 1.2.1 you should reboot your device by using the normal power button and "Slide to Power Off" swipe. USA T-Mobile users need to disable 3G mode in Settings:General:Network.

  3. уже писал в соседней теме
    айфон 4 американец
    прошивка 4.0.1
    модем 01.59.00

    напишите смогу ли прошиться этой прошивкой?
    какая последовательность?

    если через кастом-прошивку, которую нужно как я понял создавать самому, то есть ли инструкции по созданию?

    Спасибо!!!
