This from a reader: “http://www.mobipocket.com/dev/beta/j2me.asp, an early release of
software… will read .mobi / .prc files on a regular cell phone
that supports java, in my case, a Sony Ericsson C510.”

Always glad to know—and pass on!

That’s link.

They do warn it’s an alpha release and could crash your device, so take precautions and back up, back up, back up. The reader who reported he is using it did not report any trouble.
