iH8sn0w’s popular jailbreak tool for Windows, Sn0wBreeze, has been updated with support for an untethered iOS 5 jailbreak on the iPhone 3GS. iOS 5 is still in the Beta 1 stage, and Sn0wBreeze Beta 2 is the first method available for an untethered iOS 5 jailbreak on the iPhone 3GS.

Thanks to the old bootrom on the 3GS, users can enjoy a fully untethered iOS 5 Beta 1 jailbreak with the newly released Sn0wBreeze update.

You can download Sn0wBreeze Beta 2.8.2 from our iPhone downloads page.

Sn0wBreeze is only available on Windows. To learn how to jailbreak with Sn0wBreeze, refer to our tutorial.

Sn0wBreeze was updated about a week ago with support for the iOS 5 Beta 1, and RedSn0w was also updated by the Dev Team with support for a tethered iOS 5 jailbreak. Most likely, RedSn0w will be updated soon for Windows and Mac with support for this untethered iPhone 3GS jailbreak now present in Sn0wBreeze.

Let us know how Sn0wBreeze Beta 2 works for your iPhone 3GS on the iOS 5 beta. Remember, untethered support does not yet exist for the iPhone 4.
