Good news is coming for those who accidentally or mistakenly updated their iPhone 3G / 3GS / 4 on iOS 4.1 and lost the ability to unlock the phone with Ultrasn0w. A new unlock solution is being worked on and it’s confirmed by Sheriff Hashim. Tweet indicates that Sheriff Hashim found an exploitable baseband crash. An unlock will very likely be released after iOS 4.2 and will unlock both basebands of iOS 4.1 and 4.2.
Warning: Stay away from iOS 4.1 and iOS 4.2 as they may be unlockable by Sheriff Hashim discovery
and it will take months before an updated ultrasn0w release in the wild.
