pineapple logo just appears.? So I jailbroke my iphone and uploaded Cydia onto it... then I decided that I didn't really want Cydia anymore, so I pressed the restore button under Settings-->General and completely erased my phone. When the phone went back to restart, though, the pineapple sign came up and it just stays there frozen. I tried plugging the phone into the computer to see if the computer would recognize it so I could resotre it there, but it didn't. What do I do?
