The recent ice storm disrupted many Internet connections in Arkansas and I have a client that really needs Internet access. WMWiFiRouter has allowed them access in the meantime. We logged a DD-WRT router onto the cell as a client and then shared the connection throughout the wired network. Speedtest.net shows the AT&T 3G connection is giving downstream of 1.5 mb , 300kb up. Not blinding fast, but adequate.

If you have a WM phone (check their list) and travel with a laptop, this is a great solution.

Make sure you have an unlimited data plan for the phone.
