Mobile Phone to Network

I've got ADSL operating behind a router, a WiFi access point is
plugged in to the router.

Currently my main connection is a Laptop running XP Home (SP2) via a
WiFi adapter; this computer also has a USB BlueTooth adapter.

This is more curiosity rather than an actual need but I would like to
connect my Sony Eriksson Z600 phone to the network using its BlueTooth
facility (Might be useful for email options).

If this is possible I'm thinking I may have to bridge the BlueTooth
and WiFi network card connections as obviously the phone will have to
use the laptop as a gateway.

Anyone done similar or can give me some pointers.
