I received my 700p yesterday. I am upgrading from a 600 so I love all the new features. On my 600 I used PDAnet and my vision connection to allow the Treo to serve as a computer modem. The PDAnet version for the 700p is not out yet. I tried the Sprint program for the 700p and, of course, to get it to work I had to agree to pay Sprint an extra $25/month. After i did that I found the following article.

This article describes how to use the 650 and Windows DUN to acces the modem w/o paying for the teathered connection. I created a new dun connection, had it dial #777, used the word web for both the user name and password. I was able to connect teathered to the usb cable from my laptop to the 700p. The speed was comparable to the sprint software. What I don't know is whether this would have worked if I hadn't upgraded the service. Has anyone tried to connect through dun either tethered or BT without paying for the upgraded service?
