I just wanted to give everyone a heads up that FoxFi doesn't seem to work on a stock DNA. I installed the latest version of FoxFi as well as the add-on, but when activated I get a message saying that I need to have a tethering plan, and to call 611 to set it up.
Also, FoxFi isn't 100% free anymore, it has a usage limit before you need to close and restart it. The full app costs $6.97.
Hopefully once we get root we can get a root-based wireless tethering app to work.
