Nokia N-Gage QD
New QD
There is a company that does make a Bluetooth camera that you could transfer pictures to this phone with but I do not know the name of that camera. You will have to do a google search on it. I did read a couple of reviews when it came out about 6 months ago. The reviews were not kind.
Based on what I have seen from the quality (or lack of it) of pictures that come from camera-phones I suggest you buy a stand alone digital camera and just transfer the pictures from your PC (or Mac) to the n-Gage. You will get far better pictures.
The same people that think camera-phones are a good idea are kids of the same people who thought digital watcher were cool in the 70's.
