Yea a psp version would be very cool.. Since it's more portable friendly then a iphone >.< I hate touch screen stuff while playing a game..
But then again am not sure if the terms would meet for sony gaming inc.
For one it would be an issue cause sony would want to sell the game for a high price. Unless they add it to a psn store.
But then again you can make a homebrew version of it

for custom firmware.. But the only issue is i have not yet seen any homebrew games that connects to wifi.
mabey i'll post up something on pspupdates and see if anyone can port iphone app to psp >.<
