Yesterday we reported JailBreak of iPhone iOS 4.0 here. Now we got Unlock for iPhone Running iOS 4.0 with Blacksn0w from Steve, the guy who was behind PushFix 2.0. This version of blacksn0w is basically a repackaged version of the original unlock released by geohot, and the binaries which were recently released by MSFT Guy.

Steve posted on a forum post that he implemented the binaries which were recently released by MSFT Guy for 05.11.07 baseband on iPhone 3GS, running iOS 4.0 GM into GeoHot’s Blacksn0w, and he also mentioned geohot also gave him permission for distribute this version. Though it’s not official yet.
