I have just bought an iPhone 4S, not because I was unhappy with my 3GS in any way but because my other half needed to replace her faulty 3GS and the most cost effective way of doing this was to buy a new phone through work with a substantial discount and corporate pricing. As expected, the phone does everything the old phone did but just a little bit faster in a way that does not matter much. The exception is the difference in camera quality, the new phone having far superior capabilities. Given that I am a photographer, this is clearly of interest to me. Here is my first photo,a very simple image with minor tweaking on the phone before posting. Impressive I think.
