A:Answer"Open-Box" basically means that someone has opened the box, but not necessarily used the device. The device may have just been used as a floor model in a Best-Buy location. It may also mean someone already purchased the iPad and returned it. Typically, "open-box" devices will not be used (more so they will just have been looked at).
