Nokia Java Runtime 2.0 for S60 (JRT 2.0) is a totally re-written Java mobile execution environment for Nokia S60 devices. It gives you several usability and performance improvements, including:
  • One-click application installation
  • Improved application launch user experience
  • Improved execution performance

These improvements will make it much more fun for you to enjoy the thousands of games and apps available in Ovi Store and elsewhere.

In addition, we have made major changes under the hood. From now on, Java Runtime will be developed and released independent from S60 releases. This means that you will always get the latest version directly to your phone, using the built-in Nokia S60 Software Update functionality.

Compatibility and system requirements
S60 5th Edition: Java Runtime 2.0 for S60 has been tested with following devices:

Nokia 5800 XpressMusic software versions 20.x.xxx and 21.x.xxx
Nokia N97 software versions 10.x.xxx and 11.x.xxx
I'm sure Java developers will be the first to test this release. There are bug report and discussions channels open for this release on the Beta Labs forum and you can of course discuss more technical and development oriented issues on this thread as well.
