why would it need in inbuilt dialer or need sim card? if it works on wifi,it would work like a pc's wifi which connects to your wifi router,a mobile phones these days can act as a internet wifi network and access to the net for it even. you could drag it to maccas to do your update if you are the only person in Aus not to have a wifi router or a smart phone.
having it wifi is brillant idea, it probably even allows for world wide scoring if thats the case just like a xbox game. i said this before about stern, why dont they have a server settup with their pinballs connected to it via wifi so you can compete against the world
