the t809 can be used as a [slow] modem for connecting to the net via dial-up..
this is done via the "GENERIC MOBILE SCRIPT" found at
http://www.taniwha.org.uk/
THIS ONE:
Generic Mobile Phone Scripts (9kB): Generic Scripts - Third release, creating slow & fast scripts; should work with most phones, whether GSM, CDMA or TDMA. These scripts use minimal set-up and configuration commands, and leave the rest to the phone's defaults. They may well report false connect speeds like 19200 or 230400 - do not trust the reported speed!

Install that, set you phone as a USB modem is the phone settings [instead of mass storage], go to system prefs, enter the dial up account info, go to modem and there should be generic listed on the modem scripts 🙂
