Wow, looks cool. It really isn't that complicated if you think about it... It just has to be a chip that can run RedSn0w or blackra1n... But I doubt he's got the Windows libraries on there. There isn't a Linux version of any of these tools, is there?
Maybe he implemented his own exploit... Or maybe he got a go ahead from GeoHotz and got the source to compile on his IC.
That would be my only question, where he got the exploit from.
