I’ve seen a lot of projects like this, but this one has some nice twists: they modify a cheap router that runs the OpenWRT firmware to open up one of the internal serial ports to connect it to the cell phone via a cheap data cable, and then add a bunch scripts to make ppp work through the cell phone, and then share the connection via wireless. Very neat, and points out that T-Mobile has some cheap unlimited data plans.
Probably could do the same thing with the WRT54GS routers like I have too.
