It does infact work with Vista, thats whats on my laptop now....Im not sure about windows 7 though. I did have an issue with my phone internet sharing, and I read the internet sharing registry hack and that fixed it...It just stopped working one day and I had to do the reg tweak. Let me see if I can find the link to the post...
