iPhone Dev Team pushed out updated version of Ultrasn0w incrementing the version to 1.2.2 allowing software carrier unlock for iPhone 4, 3GS and 3G running iOS 4.3.2.

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.

As expected Apple iOS 4.1 download is now live and can be downloaded from the direct links provided at the end of this post, a summary of new features is also listed after the jump.

Another popular jailbreaking utility for Windows Sn0wbreeze got updated to v 1.6.1 supporting the latest iOS4 release, if you are thinking why Sn0wbreeze is needed when we already have redsn0w to jailbreak the newest Apple mobile OS - the answer is Sn0wbreeze lets you create custom firmware IPSW files on Windows (similar to iPhone Dev Team's - PwnageTool utility For Mac) letting you upgrade your devices keeping the older bootrom.

Apple iOS4 is finally out and so does the jailbreaking and unlocking utilities, the iPhone Dev Team has posted updates to their iPhone Jailbreaking utility redsn0w and carrier unlock ultrasn0w to support the newest iOS version with latest baseband (05.13.04) - this means that users can now safely update their iDevices to current iOS version without worrying about loosing there unlock and jailbreak ability.
