Speaking to numerous sources in various telecommunication companies (non Apple) the great news is that if you've pre-ordered you will be guaranteed a handset around the dates you were told. The iPhone 5 has been a phenomenal sales success story and demand had meant that you will not be able to queue outside non Apple stores early to pick one up. All stock delivered to stores has been to fulfil pre-orders. By all means try but just don't be too disappointed. If it was me I'd head to Apple directly as soon as possible. Even staff have been amazed by this shortage. Just to pass on my thoughts.
