Phone as Modem for PPC 6700

[Rob83]

I had someone tell me at a Sprint repair store that there was a website to download a file that had every thing needed to use my phone as a modem with my laptop. I found it, downloaded, and used it for quite awhile. I have since had to take down my hard drive and re-install windows from another problem.....But I cant remember where to find that phone as modem free download. My phone is not coded to use as a modem, but apparently this download--it didnt matter. Anyone have any help for me here? Thank you.
