I am very excited to announced that we have posted an early access release of the JavaFX Mobile runtime to enable people to begin developing and running JavaFX applications on real devices! The runtime package is designed for use with select Windows Mobile handsets and also includes the Sun Java Wireless Client, giving you everything you need to get started today. While we've tested (and will be supporting) this package on the HTC Diamond and the LG Incite, you may be able to run it on other Windows Mobile devices as well, although your mileage may vary.
If you purchased an JavaFX-enabled HTC Diamond at JavaOne, we recommend that you update your device to this release. Although not required, you may also want to uninstall your previous release before installing and then make sure you install to "internal storage." We still have more work to do and will be updating this stack again in the future, but go ahead and grab yourself a copy, have fun, and talk to us about it!
