Ive noticed that since I jailbroke my iPhone on one computer that I can not just tethered boot it from another. Am I doing something wrong? I copied the whole torrent file from the other computer onto a geek stick and moved it over to another laptop. When I go to just boot it gets to the point of holding down the home button and normally it stops around 8 seconds but on the other computer it just counts all the way down and then says a device is not connected. Any thoughts?
