tethering question

[bubbaflamm]

I just got a new touch pro today, and finally got it working right (the first person i talked to at sprint to activate it, messed some things up). now i'm trying to figure out tethering. I followed the instructions in post 3 of http://forum.ppcgeeks.com/showthread.php?t=59882 and am able to connect, but there are some changes from what i saw when i was connecting with my mogul.

on the mogul i had 2 drop-down menus in internet sharing: "PC Connection" and "Network Connection." the latter let me choose between sprint pcs and PAM. now on my touchpro there is only the "pc connection" menu. when i go menu>connection settings>advanced tab> select networks it shows as useing the "sprint" network (not sprint PCS).

is this working right, or am i going to be hit with huge usage charges? am i seeing what i am supposed to be seeing?
