As long is your screen is a decent size, CF isn't too bad on a cell phone...the hard est part IMO is typing everything, though that may be because I use a 12-button keypad and T9. (Ericsson W750a)
The main issue is load times. If you are on AT&T's crappy EDGE network so you don't have to pay $35 for the same $20 iPhone plan, it takes quite a while.

I'd be hugely surprised if there wasn't. I use it on my SE C903, used it on my K750i and my G502, i don't touch the PDA version it's too lite for my liking.
