As soon as the iPhone came out I wondered, "What will be in the next one that will make all the people that have one now upgrade." There were a few ideas, better camera, better GPS, etc. Obviously adding a video camera to the 3GS was a huge step. It wasn't enough for me to switch, but it was enough a product change that I considered it. Here are some thoughts about what people want in the iPhone 4.0. So far, it focuses almost entirely on the OS. I'm curious, though, are there any hardware changes that would be especially exciting for you? (OK, OK, besides battery life.)
