If you’re still hoping to pick up an iPhone 5s from your local Apple retail store, developer Mordy Tikotzky has put together a web app to help.
Just go to the iPhone Check website, put in your ZIP code (it’s US-only at present), select your desired color and carrier and hit the Submit button. The web app carries out the search for you, screen-scrapes the results from apple.com and then presents a neat, color-coded table of results.
Apple briefly introduced an in-store pickup option, pulled it after one day and restored it a few days ago. The tool is a very handy way to check availability, but if my quick tests are anything to go by, you’re still not going to have much luck finding a gold one (other solutions are available …).
