I have the Keon from geeksphone. The Mozilla developer site talks about using the emulator, but nothing about installing an application onto a physical device. It is a developer phone, so I assume there's a way to develop with it? I can host the app and test it in the phone's browser, but I'd prefer trying to package it up and actually install it onto the device.
Found it. Now I need to figure out how to install an XPI file...
