Flickr keeps tracks on the cameras used to take the pictures hosted on its site. It's a great way to see what the popular tech is in any given month.
It comes as no surprise to see that Apple has done really well. The standout success story is the iPhone 3G which has had about 120 times more uploads the iPhone 4. That's 28,176,526 compared to 240, 429 at the time of posting.
The Evo 4G beats the iPhone 4 for uploads. Is that a surprise?
The usage graphs also show an interesting picture. The amount of uploads from the iPhone 3G are dropping - not surprising given the age of the phone and the iPhone 4 is increasing.
