It should be interesting to see the iPhone 5 numbers when they come out. If it does worse than the 4S, could this accelerate plans for a redesign? If the numbers are weak, I can't say I'm surprised with the lukewarm response with the iPhone 5 design, which is like a less than exciting evolution of the 4/4S design. We'll see what's really going on here when more data comes in. As some have mentioned, it could also be a iOS problem.
