The iPhone Dev Team has released their much anticipated iPhone 3GS unlock. Last week we reported on George Hotz, the teenage hacker, who released a Windows only version of the jailbreak, and then a Mac version over the weekend. The iPhone Dev Team jailbreak isn't much different then Hotz's version — besides the point that the iPhone Dev Team released it, and not a 3rd Party. The Dev Team is a group of hackers dedicated to unlocking the iPhone and exposing all of its wonderful mysteries.The 3GS jailbreak, codenamed "ultrasn0w," uses the same procedure as the iPhone 3G unlock process. The Dev Team in a blog post also mentions that if you have the correct personalized (signed) dfu/img3 files, then you'll always be able to jailbreak, even if you install Apple's firmware update.
