If you have t-mobile...
Setup a bluetooth modem then use this info:
Telephone #: *99#
Account Name: your cell phone #
Password: whatever your password is that you use to login to t-mobile.com.
Under the configuration for the modem, in the TCP/IP tab (this is in networking, then you choose the bluetooth option and do configure) - Configure IPV4 should be "using ppp"
under the ppp tab you put the info i have above, and under ppp options turn off echo packets.
no need for proxies, under bluetooth modem, you choose "ericsson infrared" enable error correction, wait for dial tone.
This is how i got my t610 to work in hawaii when i'm on the beach.
PS - the phone needs to be paired before you do any of this.
Have fun. Ask if you need anymore help.
PPS - This is for using wireless internet, not dialup. I highly suggest it - I think it's 10 bucks a month for unlimited http/imap/pop3. If you need other things I think the 20 buck plan is unlimited everything. I typically get about 4-5kB/s, the only issue is latency, takes a bit for those packets to go around.
