Just letting you know, that one of the Siemens developers at JavaOne last month told me that starting with Firmware #11, the SX1 will support Java/Bluetooth together (JSR-82) .. this means, that Java developers NOW have access to the Bluetooth radio in the Siemens SX1 (so long as it's using Firmware #11 or higher) ... this is NOT MIDP 2.0, just the JSR-82 spec. has been implemented.
We have tested it and it works ... Thanks Siemens!
