Ultrasnow 1.2.1 Unlock for 4.3.1 | iPhone 4 & iPhone 3GS
Remember, in order to unlock your device with Ultrasnow 1.2.1 for 4.3.1 you must update your iPhone4, 3GS to iOS 4.3.1 with Snowbreeze 2.5.1 or PwnageTool 4.3 that will preserve your old baseband.
Ultrasnow 1.2.1 unlock for 4.3.1 works on iPhone 4, iPhone 3GS and iPhone 3G with the following basebands:
- 01.59.00
- 04.26.08
- 05.11.07
- 05.12.01
- 05.13.04
- 06.15.00
However, there is an alternative solution to unlock iPhone 3GS & iPhone 3G that have the newer basebands, by upgrading their baseband to 06.15.00. In order to do that you can follow the tutorial posted here and then come back to this post and proceed with the unlock.
