Phone bill too high?

This well may be old news, sorry Roddles if it is, but please feel free to
abuse me. I deserve it, and I know it helps you as well.

Read a couple of days ago that Bluetooth has been hacked to such an extent
that sniffers can locate a phone running Bluetooth, and even dial out on it,
unknown to the 'phone owner.

Nokia 6310 and 6310i series the most vulnerable, other Nokias also
vulnerable; Siemens at this stage cannot be hacked.

Sort of lost the thread (it was 03:00 and I was sleep walking), but some
info here:-
