As far as I know, it only works with an iPhone 4 because that has a processor quick enough to handle the app.
Curious how much it will cost, a 57" TV already costs ~€8000, and that's without a touch interface or iPhone connection. If it tops €11.000 it is going to be more expensive then the Microsoft Surface table and might seriously hamper the amount of units they will sell. The positive: It isn't as deep, thus could easily be used as a table, uses the iOS software (thus you can use iPhone apps without modification) and is a far larger surface (58"vs. 30"). Limited resolution (960x640 vs 1024x768), not as much interaction possibilities as Surface (recognizes opjects placed on the table).
