Ultrasn0w

The iPhone Dev Team has posted a notice for iPhone 3GS owners hoping to jailbreak. A jailbreak will be released relatively soon, they say, but certain files will be needed. They have a new, more reliable method for obtaining these files, but it will only work if you do it before Apple releases another update and if you don't have the OS 3.1 beta. It should also be noted that this method may update you to the 3.1 beta if it's on your computer, which would remove your chances of using Ultrasn0w in the future.

The Dev Team posted a warning on their blog reminding users that if you want to maintain the ability to use the Ultrasnow unlock for the 3.x firmware, don't upgrade to anything past 3.0, including the recently seeded developer copy of the OS 3.1 beta. 3.1 updates the baseband, breaking the ability to be unlocked by the Dev Team's exploit. The warning applies only to 3G and 3GS devices.

The Ultrasn0w OS 3.0 unlock for the iPhone and iPhone 3G demoed last Friday is now available in Cydia and Icy.
