I just bought a used and broken screeniPhone 4s. Apparently, this iPhone has screen locked(requires 4 digi password). While this iPhone was charging with "Scosche brand RCA tv plug". I typed the "wrong password" first time then hit emergency call. Then the screen showed "this accessory is not supported", then "ignore". Until the camera icon on the screen showed up. Hit camera icon, then hit lower left corner for reviewing photos. BINGO, I can see all pics! If I don't input "wrong password" the first time. The photo album is locked. I'm guessing the first "wrong password" and an unsupported "Scosche brand" charger does the tricks!
