I got a T-mobile home internet gateway a few days ago when my wife noticed her hotspot suddenly had four bars rather than the zero to one it used to get at home. The new device is free with the no-contract, no throttles, no caps $50/month service. Of course, "no contract" is a two-way street and they can change the terms at any time.

The gateway worked beautifully out of the box, but I wanted to connect it to my home network. A little Googling found the trick, and today devices in the house and the apartment over the barn connect the same as they did before. We've been paying $150/month for a local microwave broadband service plus $30 for a backup DSL line. I can definitely drop the microwave and will also drop the DSL if this keeps working. It's like joining the 21st century.
