Hello! About 2 months ago, I've lost my iPad, that was updated with iOS 4.[something]. I locked it with "Find My iPhone". I found my iPad after a week (and it wasn't locked) and just recently I've updated it to 5.0.1... but then the locking was activated... and I don't remember the passcode... so what can I do to start it from scratch or somethig without opening it? how can I solve this?
