HI! I just had a photo shoot a while ago using 6260 and 6600 to compare the image capability of these two phones.
The pictures that you'll going to see are raw images from the two phones. No editing. No software intervention. Both are taken under similar condition. Same distance.
Here are the links:

My verdict based on these two photos: 6260 is much sharper than 6600... But then again I noticed that the 6260 photo became closer after being transferred to the PC. We all knew that if the object is closer, the sharper/clearer you will get.
