Look at this from the the George website lol
Q: When will you release a version of PocketGeorge for NetOS/iPhone/Andriod/Symbian/whatever...?
A: We will probably support a Smartphone operating system at some point but it almost certainly won't be the iPhone as it has too small a market share.
It will probably be Android but Nokia are going to start making Windows Phone 7 handsets - which will probably make a big difference to the market.
Also, HP have announced they were going to start developing devices for the Palm NetOS platform. If HP release the "Classic" emulator these devices would run PocketGeorge unchanged.
