Sn0wbreeze 2.3 Beta 4 For iOS 4.3 Released; Allows Users To Unlock iPhone 4 Baseband 01.59.00, iPhone 3GS Basebands 05.13.04 Or Earlier Using Ultrasn0w

Sn0wbreeze v2.0

iH8sn0w has released a new version of Sn0wbreeze – v2.3 Beta 4, which will allow users to use Ultrasn0w to unlock iPhone 4 baseband 01.59.00 and iPhone 3GS basebands 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04.

iH8sn0w had released Sn0wbreeze to jailbreak iOS 4.3, the unofficial PwnageTool for Windows last weekend.

Sn0wbreeze 2.3 beta 4 includes the following changes:

  • ultrasn0w now works for basebands (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00)
  • ultrasn0w is NOT compatible with the folllowing basebands! (02.10.04 / 03.10.01 / 04.10.01 / 05.14.02 / 05.15.04)
  • Upgrading your iPhone 3GS baseband to the 06.15.00 iPad baseband hack to unlock MAY cause you to lose your GPS!
  • Fixed minor GUI + iBooty bugs.

Sn0wbreeze is useful for users who have their iPhone on older baseband (iPhone 4 baseband 01.59.00 and iPhone 3GS basebands 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04) and want to unlock their iPhone as it allows users to create custom iOS 4.3 firmware file that is pre-jailbroken, which can be used to preserve the baseband from getting upgraded using the “Baseband Preservation Mode” so that it can be unlocked using Ultrasn0w. You can check your iPhone’s baseband via Settings –> General –> Modem Firmware.

Sn0wbreeze 2.3 beta 4 supports only a tethered jailbreak currently so users will have to use iBooty to boot into jailbroken state (which is installed on your desktop after running Sn0wbreeze 2.3) if they need to reboot their iOS device.

Sn0wbreeze 2.3 supports the following devices:

Sn0wbreeze is available for Windows users. iPhone Dev Team is yet to release PwnageTool to jailbreak iOS 4.3 for Mac users. There is also no software solution to unlock iPhone 4 basebands – 02.10.04 (bundled with iOS 4.1), 03.10.01 (bundled with iOS 4.2.1), 04.10.01 (bundled with iOS 4.3) or iPhone 3GS basebands – 05.14.02 (bundled with iOS 4.1), baseband 05.15.04 (bundled with iOS 4.2.1) and baseband 05.16.00 (bundled with iOS 4.3).
