Why? 240 × 320 @ 100fps? What would you want to record at that small of a resolution? According to its specs LG KU990 VGA 640x480 is only at 30fps. The N900 specs is shown to have 25fps at 848 × 480 which is about 1/4 more pixels (which is a lot -- for only a 5 frame loss). So I don't know if the camera is "locked" to a certain speed on the n900, but if it isn't is should easily be able to handle 320x240 @ well over 100fps... Nathan.
