I think the megapixel number the phones have is something to do with there screen res aswell, probley why there is only 1.3 , 2mp , 3.2mp , 5mp , 8mp , 12mp , where on a digicam you can get anything where your more likely to print them off and view them on a proper screen i have a 7.1mp canon ,also phone & digicam manufactures want to get the maxium megapixels than can on the sensor. if a bigger sensor and proper lens are used then the results are alot better i use a casio EX-Z1080 it has a 1/1.75" 10mp ccd sensor and some special lens, results are below.

Mega-pixels are a double edged sword, they give useful resolution if you want to crop your photos. But if lots of mega-pixels are crammed on a tiny sensor, like the ones on phones and compact cameras, then the sensor won't get a good signal and you will get noisy images at even the camera's lowest sensitivity.
Ideally the sensor manufacturers should aim to get the best quality in daylight conditions, with little noise, camera phones and compact camera's wont get good results in low light.
