I thought I had left an iPad in a hotel room and after checking with the hotel and finding they couldn't locate it, I locked (?) it so hopefully if it had been stolen that it couldn't be used. Recently while packing for a trip I discovered that iPad in a piece of luggage I had looked twice in that luggage, but didn't see the black bag in the black luggage. Now my question. Does anyone know how to unlock this iPad or am I going to need to go to an Apple store or elsewhere?

Thanks Doug! I knew some 170 person would have the solution.
