UltraSn0w Unlock Working Fully on iPhone 4.2.1

A couple days ago we informed you that the UltraSn0w unlock for iPhone iOS 4.2.1 was supposedly going to drop this Sunday. According to a recent tweet from Dev Team member MuscleNerd, it seems we are on the right track for a release on schedule.

This UltraSn0w unlock for iOS 4.2.1 will work with the iPhone 3G and 3GS. It will not work with the iPhone 4 yet, but it’s being worked on…

A few weeks ago, the Dev Team had claimed that UltraSn0w would be available shortly after the release of iOS 4.2.1, but there was a slight plan change because it needed some unexpected updating.

UPDATE: UltraSn0w unlock for iOS 4.2.1 is available. Click the link for more details.
