Speaking of iPhone jailbreaking, the iPhone Dev Team has now gone live with their redsn0w iPhone 3GS jailbreak, something they were holding off on doing and waiting for the iPhone OS 3.1 update reports Intomobile.
Redsn0w replaces QuickPWN and preserves the iPhone 3.0 baseband for future iPhone OS releases which is important for people who want to unlock their iPhones at a later date. Once you have jailbroken you can then use ultrasn0w to unlock your iPhone.
We have a video demonstration for iPhoners on unlocking the iPhone 3GS, which can be viewed below, so hit it up and enjoy.
