Internet Sharing, Phone As Modem

[static110]

I am getting my Treo Pro friday, and use this all the time on every smartphone I have had, but will I need the Internet sharing fix from the mogul also? I know when I had the touch pro, the internet fix greyed out the option for me to use it. I had to do the regedit like the 800w. But my touch pro would drop the internet constantly, but the vogue is the best next to the mogul that I have found so far.
Dont know if any of this helps, but gave some info..LOL
