Is it real or not? Have to wait and see.

It may be real! Geohot may surprise us (again!) with a new unlock solution for iOS 4.1 and iOS 4.2.1 on iPhone 4. The video below shows iPhone 3GS running iOS 4.1 on baseband 05.15.01 unlocked using Limesn0w solution via Limera1n jailbreak which was released a month ago. It would be a real surprise.

Of course there's a lot of users have updated to iOS 4.1 and now their devices on baseband 02.10.04 or higher which is not unlockable at the moment. So Geohot may really surprise us Limesn0w.
The domain is registered by Geohot, the same info as but the site indicates that "This will never be real.", you know, surprises! Geohot didn't say any word about that, we'll keep you updated at any update happens.
