A new video shows up on YouTube, which presents GeoHot’s BlackSn0w ported to iPhone OS 4.0 Beta 4. This port works in CommCenter and allows you to unlock baseband 05.11.07 however, the hack is very buggy ( i.e you will have to run the patch everytime you reboot your iPhone, in order to use your phone network ) .

At the end of the video you can see a mediafire link from where you can download the patch , but we advise you to take no action and expect a release ( or further info ) from the iPhone DevTeam or GeoHot.
We will inform you as soon as an official tool will be released. Stay tuned…
