applications. It is used when running Java based applications on your mobile device.

The latest version, Java Runtime 2.1, is now available for S60 5th Edition devices as a Beta release.

JRT 2.1 Beta provides developers and end users early access to the latest mobile Java features including:

* Improved installation user experience
* Improved MIDlet start-up experience
* Improved security user experience

Important: Since Java Runtime 2.1 Beta is beta-level software, it has not been thoroughly tested on all S60 5th Edition devices.

The following S60 5th Edition devices and firmware versions support Java Runtime 2.1 Beta. These have been used as reference hardware during beta verification.

* Nokia 5800 XpressMusic, 40.x.xxx and newer
* Nokia N97, 12.x.xxx and newer
* Nokia N97 Mini, 10.x.xxx and newer

The final Java Runtime 2.1 release will be compatible with all S60 5th Edition devices with the latest firmware.

Before installation

Before installing JRT 2.1 Beta, make sure that:

1. Your device has the recommended 20MB of free disk space on the C drive

* Java Runtime 2.1 Beta binaries require only 4MB, but the conversion of existing MIDlets requires additional disk space.
* In order for the device to function properly, it must always have some disk space available, otherwise the device may become slow or unresponsive.

2. Your device has the latest available device firmware installed

* Java Runtime 2.1 Beta has a dependency to OpenC libraries, and there are known issues with older OpenC library versions that are part of earlier S60 5th Edition device firmware.

Installation notes

* The MIDlet conversion may start after the JRT 2.1 Beta has been installed. The conversion may take a while. DO NOT CANCEL THE CONVERSION. If you cancel the conversion, for example by removing the battery, the MIDlets may become inoperable. Make sure that the battery is not depleted during the conversion.
* You can install JRT 2.1 Beta on top of JRT 2.0 Beta.

Uninstallation

* You must reboot your device after uninstalling JRT 2.1 Beta. This restores the original Java Runtime environment of the device.
* MIDlets installed after installing JRT 2.1 Beta will be uninstalled as part of the uninstallation of JRT 2.1 Beta. There is no way to circumvent this.
