I'm wondering what's causing the huge increase in demand for the iPhone 4 over the 3S last year. When I ordered my 3S on day 1, it just took one try. This time I had to wait a day to get through. Now I'm reading about the huge demand for the new phone. Why? What's different since the launch of the 3S last year? Is it because of the new features? Front camera? LED flash? Hi resolution screen? Gyroscope? Is it the new OS version? Slight multi-tasking? App grouping in menus? Gaming network? Is it the physical styling of the new phone? Is it the iPad aura that's carrying over to the new phone? Are there notable apps available now that weren't available last year? Something else? I really don't get it. I don't see much different since last year. I've bought all the iPhones early, and I've never seen demand like this. Btw, is the same thing happening with other platforms, like Android? Maybe I just don't notice since I've committed to the iPhone, and don't pay close attention to the others.
