All, Have you noticed an extended 'hiss' noise(it last about 1 to 2 seconds) after the standard 'tick' sound whenever you interacts(eg. select item) with the touch screen? I did not hear this 'hiss' before and I had the same sound configuration before the reflash. Is this a bug? It is no big deal, but I guess it would reduce battery life, since it still takes some juice to generate the noise I have 'level 1' for all the sounds level configuration on the unit. I have N800. I flashed the unit to Diabio and then did the SSU update. Cheers,
