I did some searching around on the Internet and came up with the following to get my TomTom GO 920T working with my Treo 755p. Now I can get traffic and weather through my Sprint Palm Treo 755p.
I used these instructions to get the 'Tethered mode hack' onto my 755p.

IMPORTANT DISCLOSURE: I THINK this setup will use your data connection in a Phone As Modem (PAM) configuration, and YOU MAY BE BILLED EXTRA by Sprint. The reason I think this is because of the need to enter #777 as the number to dial for the data connection. This is the same number you use when making a PAM connection from a laptop, for example.
You've been warned!
Here are the manual settings I used on the TT:
Phone Model: Treo 650
Mobile Carrier: Other
APN: proxy
Phone # to dial: #777
username: <leave blank>
password: <leave blank>
IP Address: Automatically assigned (DHCP)
DNS: Automatically assigned
Login Script: <leave blank>
Those might not be in the same order that it asks you, but I think it's all the items it asks for.
Once I entered all that info the 920 then recognized the features of the 755p that it could use, including 'hands-free', 'wireless data' and 'phonebook'. 'Phonebook', it turns out, is not all of your contacts, but seems like it does include the recent call history and anything you've got set up in your favorites buttons.
