Ultrasn0w For iOS 4.2.1 To Unlock iPhone 3GS, iPhone 3G To Be Released On Sunday

We have some good news for folks who want to unlock their iPhone.

MuscleNerd of the iPhone Dev Team has just confirmed that the eagerly awaited unlock for iPhone 3GS and iPhone 3G for iOS 4.2.1 will be released on Sunday.

MuscleNerd announced the good news via the following tweet:

Good progress today…everything is on track for updated ultrasn0w by Sunday/Funday at the latest (longer for iPhone4!)

iPhone Dev team had mentioned earlier that the unlocking solution for iPhone 4 users will need more effort and were not in a position to provide any further information.

The updated version of Ultrasn0w will unlock baseband 05.14.02 that was shipped with iOS 4.1 or lower.

However, it is not clear if the updated Ultrasn0w will unlock baseband 05.15.04 that was shipped with iOS 4.2.1. So users who want to unlock their iPhone should avoid upgrading to iOS 4.2.1 for now. iPhone Dev Team had warned users immediately after iOS 4.2.1 was released:

As always, ultrasn0w unlockers please stay far far away from this official firmware (and all official firmware). Wait for the ability to create custom 4.2.1. IPSWs that don’t update your baseband!

iPhone Dev Team has already released a new version of Redsn0w to jailbreak iOS 4.2.1 for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 4G,iPod Touch 3G, iPad and Apple TV 2G.

As always, we’ll let you know as soon as the updated Ultrasn0w is released so stay tuned here at http://anynews-search.blogspot.com or follow us on Twitter .
