    Hi guys, I've added my UDID to my dev provisioning and everything, but every time I try updating or restoring to 4.0, I get a "this iphone cannnot be restored, error 13" message. Is there any trick to this? Does it require a mac?

    I suggest you use Apple's developer program forums, as there is a strict NDA on the matter.
