I received the following lolcat 'esque message on my pocket pc the other day.

"Bluetooth can no longer be used because the license is expired."

This apparently is a known Bluetooth software bug on ppc. The way I
fixed this issue is quite drastic, what I did was I backup all my data
to my device storage, reflash my ROM with a clean windows mobile 2003
image, then restored all data from backup.
I did have problems getting my ppc to accept the image and had to
resort to mtty to initiate bootloader commands.

It seems like my trusty old ppc is coming to end of it's life, oh well let's see how much longer I can keep it running without upgrading.
