Sn0wbreeze 3.1.3 jailbreak is Out now. iH8Sn0w released the latest installment of Sn0wBreeze 3.1.3 to jailbreak iPhone 3GS, 3G and 2G running iPhone 3.1.3 firmware. The best part of Sn0wBreeze is the ability to preserve baseband which means if you’re on an older firmware (means you’ve 05.11.07 or older Baseband) and go to firmware 3.1.3 using Sn0wBreeze, you’ll then be able to unlock your iPhone 3GS, 3G using UltraSn0w or BlackSn0w depending on your Baseband version.
If you own an iPhone 3GS, please note that Sn0wBreeze 3.1.3 only supports non-MC Models with older bootrom and plus if you have already upgraded 3GS to OS 3.1.3 you’re still out of luck. Currently there’s no support for newer iPhone 3GS and iPod Touch 3G. Sn0wBreeze is a Windows based jailbreak tool. No support for Mac sorry.
In order to jailbreak iPhone 3GS 3.1.3, jailbreak iPhone 3G 3.1.3 and jailbreak iPhone 2G 3.1.3 simply follow the step by step instruction below.
