It was only a matter of time but both Flash and Flashes are available for cell phones now.

For the Camera built into most of the current J−Phone cell phones you can now buy a flash attachment. That's pretty cool.

On the Flash (as in vector animation) well, actual Flash support is now out yet (though I suspect it's only a matter of time) but Sharp has added to their latest cameras a Flash like image format that supports vector animation. They call it E-Anime. I think page will install a plug−in in IE on Windows to preview the animations.
