Utterly ridiculous
Even if you put a 20mp sensor in, the pix would be WORSE than a 3mp.
They're crippled by lens and CCD size.
When you hit 8mp, and don't increase the CCD chip size, you get a reduction in pixel size, which thanks to the properties of light is a VERY bad thing and buggers up the pictures in all kinds of ways.
Thats why paying any extra for 8MP+ in non-SLR cameras is a foolish thing to do, you'll end up with worse quality.
Shame that this ridiculous marketing-for-morons has now infected the mobile industry.
Oh and Korea had this years ago: http://mobilementalism.com/2005/11/03/samsung-8-megapixel-count-em-mobile-camera-phone/
