I read everywhere that the PSP-3000 was the brightest model of PSP. While it is definitely higher-definition, much clearer and lighter in weight, I notice that the PSP-3000 isn't very bright at all. There are 3 brightness levels and the highest one is still too dark for me, darker than the 3rd level on my DS-Lite. Is there a way to increase the brightness level (other than the button on the bottom)?
