I have used the Comm manager that Sector ported to get wireless internet to my laptop. There is a WiFi Router built in (it's from HTC). It's finicky though. Eventually though it will connect. I was also able to connect another PPC to the internet (an iPaq, controls my irrigation system in the field, pretty cool!). It just takes some time to get it. I don't know exactly what i did to get them working, I think time and letting the prog do it's thing.
Go here to get it and read about it.
