There is a program that allows you to run your Computer off your iPhone, and through it you can run WoW, though technically it's off your computer. It's similar to how you play WoW on the Wii. It's technically not on the iPhone or the Wii. And, using the program, you could actually play D1 or D2 with your iPhone, kinda.
I think this is a legit video of WoW on the iPhone, though I'm not 100% sure, there's alot of fakes.
But yea, D3 may be ported, and D4 probably will be ported to a handheld...
Hell, you could probably port D1 to the DS... (PSP? Fuck that, Blizzard is smarter then to work with Sony!)
However, there is a company that is working on making games work on 3gs powerhouse smartphones. Don't see it working though. Just cant see it.

I know if I had the iPod Touch I would....
