Following Tokyo Disney Resort's lead, WDW has announced that beginning sometime next year...guests will be able to access park information through their personal cellphone devices. You can look park info such as where characters are doing meet/greets, how long lines are at particular rides, if FP is gone for the day or not.. etc etc etc.
Pal Mickey of course, launched the wireless craze before any park did, incliding the international Disney resorts, but Pal Mickey was never able to answer your specific questions... reason why I think they are being retired.
The wireless cellphone info service has been in use at Tokyo Disney Resort for over a month now, and guests love it. Just ask Micechatter Ichigopara... or read her thread on this in the TDR section of MC.
