I searched in the forums, but I couldn't find anything. When I select gpsphone, it brings up a blank white screen which instantly closes. Yes, I put the BIOS in the right folder, though "telling" me where to get a certified working one wouldn't hurt. And I changed the permission to 755. I have a 2g ipod touch 8gig running 2.2.1 custom firmware. I really want this before I go on a trip! Please help!
