Thanks.

The uqm devs have offered access to the original .wav files for the mp3 encoding. Actually given the size constraints, the 770 speaker is quite good: Electrostatic, very loud.

There is quite a todo list to make this package work well on the 770 / 800. I've applied for a project page (uqm) on garage.maemo.org so development and discussion can be publicly coordinated.
