I did this with my T68 via the Ericsson software & bluetooth - I have a bluetooth transceiver on my MSI motherboard.
This is basically a 2.4 GHz RF connection, similar to IEEE802.11b
(aka "Wi-Fi") but slower.
You can enable bluetooth on the T68 via the connections icon.
However, you have to have something else with bluetooth to use this (PC, PDA, bletooth USB dongle etc.).
