Hi all, I have an iPhone 4 that I no longer use. I plan on giving it to a friend because she broke hers. I haven't used this phone in nearly a year and I turned it on today having it ask me for a passcode. I have tried all the passcodes that I could think of that I may or may not have used and I am now locked out of the phone for 60 minutes. I have tried syncing it up with my laptop but it doesn't register through the USB port. Is there any advise anyone could give me or should I just go to an Apple store? Thank you.
