Thanks for your input.

I also tried setting the clock back with no success.

Do you know of any other JSR-82 implementations out their that could be experimented with to try and get a BT MIDlet running on a PDA?

I have been in contact with atinav, and the price to purchase a non-commercial/prototype licence is astronomical, compared to avetanaBluetooth at just ($25). Running a MIDlet with the avetanaBluetooth JAR file in the ext directory, just crashes the MIDlet. I'll see if I can work on this problem.
