Since iPhone Dev team has released Redsn0w 0.9.6 RC9 and PwnageTool 4.3 today, iH8sn0w has come up with Sn0wbreeze 2.5 to jailbreak iOS 4.3.1 firmware on Windows platform. For those who don’t know, Sn0wbreeze is a Windows equivalent of PwnageTool.
Sn0wbreeze 2.5 uses i0n1c’s exploit to bring untether facility to jailbroken devices. Similar to above mentioned tools, this tool also supports iPod Touch 3G, iPod Touch 4G, iPhone 3GS, iPhone 4, iPad 1 and Apple TV 2G.
Unlockers, please read the following guidelines -
WARNING WARNING — ultrasn0w users don’t update yet! We need to first release an update to ultrasn0w that fixes some incompatibilities when FW 4.3.1 is used on the older basebands supported by ultrasn0w. And remember once we do fix ultrasn0w for 4.3.1 (we’ll announce it here and on twitter), you must only get there via a custom IPSW from PwnageTool, Sn0wbreeze or xpwn! Don’t ever try to restore or update to a stock IPSW, or you’ll lose the unlock!
