So we will see yet another surprise from GeoHot after his limera1n jailbreak stole the show with iPhone 4 4.1 jailbreak and also caused the SHAtter based greenpois0n to be delayed. Let’s see if GeoHot has the iPhone unlock at hand.

Furthermore, a leaked limwsn0w image shows that GeoHot could surprise us with sn0w option in limera1n.

Update: GeoHot has posted a note on limesn0w.com saying:

This will never be real. Media, understand it. ~geohot
