I've seen a lot of info that Android is supposed to be completely open, and that the carriers aren't going to lock down the devices like they do with other phones. Does this openness only extend to the Android API, or can you get a shell / root shell on these devices? I'm interested if you will be able to dump Android from them and put together your own environment (based on Maemo, or OpenMoko, or QT Phone edition, for example).
