Thanks for the reply.

Bluetooth is working great with my PC and my GPS receiver (also a Holux) always connects perfectly (using TomTom and the inbuilt GPS basic app). It's just with the Supertooth handsfree. The Supertooth makers don't want to help me and the phone has the latest firmware (same as yours). So basically it's almost useless.

I'm also having connection errors - calls just drop out for no reason and the phone says "Connection Error". Hopefully that's not from me upgrading it with a different region's firmware.

It seems these smart phones are starting to go the way of Windows PCs where they need reboots and configuration or installed software can cause big problems with other functions maybe.
