There is no clip board. That is just the term used to say that the item you wanted copied is copied and that the iPad will remember it until you decide to paste it somewhere. Its not an actual thing that can be accessed. If you have used Windows 7, Vista, XP, 2000, Me, 98, 95 or Apple OS8, OS9, OSX or any linux distro or Android or iOS3.x or iOS4.x or Windows Mobile or Symbian or Palm OS, it pretty much works the same way.
