sn0wbreeze, the only iOS 4.3 jailbreak compatible with Microsoft’s operating system, was updated again earlier today. The new version of the jailbreak, released by iPhone hacker iH8sn0
w, fixes a slew of bugs, and offers a major enhancement over its predecessor: it now supports ultrasn0w unlock for iPhone 4 and iPhone 3GS (with a couple of caveats, more details after the break).
The jailbreak is compatible with iPhone 3GS & 4, first generation iPad, and third & fourth generation iPod touch – iPad 2 users will need to wait, as the jailbreak is not compatible with their device.
sn0wbreeze is a tethered jailbreak, which means that each time iPhone, iPad and iPod touch users switch off their device, they will be required to plug it to their computer to be able to restart it.
While the jailbreak allows you to preserve your unlocked baseband, if your baseband needs to be unlocked, the updated version now supports ultrasn0w unlock. Only six basebands are supported at this stage:
Note that ultrasn0w is not compatible with other basebands, such as 02.10.04, 03.10.01, 04.10.01, 05.14.02, as well as 05.15.04. Also note that some users have tried to upgrade their iPhone 3GS baseband to the 06.15.00 iPad baseband, but lost the GPS functionality – in other words, if your baseband is not listed above, walk away from this update.
Since the jailbreak is still at a beta stage, make sure to fully backup your device (including your SHSH blobs) before you even give it a try. sn0wbreeze 2.3 beta 4 can be downloaded here
Even though jailbreaking is considered legal, always keep in mind that Apple sees it as a warranty-voiding act, so do it at your own risk. Please do not use jailbreaks to install copyrighted/paid content you haven’t purchased yourself.
