So I've been reading a lot about people falling into the trouble of buying a second hand device and updating it to iOS 7, only to find out that the previous owner is still signed in with their ID with no work around? But I've been thinking, and I want to see if anyone has tried this and succeeded? But wouldn't a DFU restore bring the iDevice back to life? What do you think? I really want to try this out and help some people!
