So short story I jailbroke my itouch with spirit. It was workin perfectly. Then a couple days after the screens brightness started messing up and the screen would turn complety white. If i shook it it would temporarly go back to normal and then back to white. I did all the restores and now when i press the power button twice really fast it flashes horizantal lines. I can return it because I have a warranty but is there anyway i can fix this myself? O ya its refurbished from apple and it fell once.
