you can;t upgrade your camera. the ammount of megapixels has nothing to do with the drivers. the camera sensor is the one that is responsible for how much megapixel the camera is. the W300i camera sensor (640*320px = 0.3megapixel) is smaller than the 1.3 megapixel and much smaller than the 2 megapixel camera sensor. abd there are different sensor types. so you can upgrade your camera only by buying a digital camera :)
