The most vocal member of the iPhone Dev Team, MuscleNerd, has confirmed that the much awaited unlock for iPhone 3GS & 3G (all basebands) on iOS 4.2.1 will be released this Sunday with a new Ultrasn0w update!
Good progress today…everything is on track for updated ultrasn0w by Sunday/Funday at the latest (longer for iPhone4!)
iPhone 4 unlockers though will have to wait a bit longer before they can use their device on any carrier they like. More updates as they come! Stay tuned !
