We have loaded to the iPad at one project. Seemed to solve some lag issues. iPad responded a little smoother there.
Whatever the case may be... its not a big deal. If your program is stored on the processor then you just need to sync the app and "login" (processor ip, port, passcode). If the program was stored on the iPad... call up the crestron dealer. It takes seconds to load the new iPad and it can probably be done while you are on the phone with them.
