I use a Viewsonic Viewpad 10 with an HTC HD2 phone with a custom ROM as a wireless access point. If I'm doing anything more than a quick surf I reboot the Viewpad to Android, (It dual boots Win7 Home and Android), so it looks to my service provider that I'm using the phone because they don't like people "tethering" their laptop to the phone.
If you'd like details PM me..
