Good news for all iPhone 3G users! Sn0wbreeze 3.1.3 has been released which can jailbreak iPhone 2G, 3G and iPhone 3GS on the latest iPhone 3.1.3 firmware. It is very important to note before proceeding that it will work with iPhone 3GS only if it has the older bootrom (non-MC model). iPhone 3GS users who have upgraded to the stock 3.1.3 are still out of luck.

Update: Sn0wbreeze 3.1.3 v1.5.2 released

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 and 2G .

Sn0wBreeze 3.1.3 currently supports iPhones only. In order to jailbreak iPod Touches, you need to checkout redsn0w 0.9.4. iPod touch 3G is currently not supported by either of them.

  2. If sn0wbreeze isn’t downloading on your computer and you have norton security, it probably just detected it as a threat and quarantined it. Just open up Norton, go to quarantine and restore the file. Worked for me :)
