Thanks for the reply Marcel.

Hopefully a firmware upgrade for the phone will fix it, but I won't hold my breath. :(

The Nokia 770 works perfectly with my former phone - a Sony Ericsson T610, which is quite an old phone and not a Smartphone. Unfortunately I don't have a BT dongle for a PC so can't confirm the behaviour with a CSR chip.

I'll have a look at PAN but I'm not sure if the Nokia 770 supports this.

Finally, does anyone have any suggestions how it may be possible to contact the Symbian/SonyEricsson developers and ask them to look at fixing this? Newsgroups, web sites etc? I have a feeling contacting SonyEricsson CS will be a painful and fruitless excercise!
