The most widely used iOS software unlock Ultrasn0w just got updated by parent iPhone Dev Team to support carrier-unlocking on any baseband later than 05.13.04 for iPhone3G/3GS owners. This unlock is interestingly using the exploited AT+XAPP command security-hole which was actually plugged-in by Apple but it turned out that the very first iPad firmware 3.2.2 has baseband version 06.15.00 which is still vulnerable to AT+XAPP exploit and since the iPad baseband is built for the exact same baseband-chip as the iPhone3G/3GS what we have is an exploit with a carrier unlock for these devices. In simpler terms iPhone 3G/3Gs owners can unlock their devices running iOS 4.1/4.2 but there are some risks as posted next.
