I also think it's a software issue but i'm a little worried about it.

Yesterday i thought on something else: Every mobile phone with MMS is able to record in low resolution (to be able to send it).
With the features available in the N900 in camera mode, the MMS function seems to be really far away since you will need to create links between the camera and the message feature so when adding a multimedia element to you SMS, the phone will be pre configured to create 30sec clips in low resolution (under 300k) and pictures in VGA mode.

I know nothing about software (i am a director) but what do you say?
