Tech giant Apple's (NASDAQ:AAPL) all-important iPhone release is just days away. As the company typically does, Apple opened the iPhone to pre-orders the week before it was set to ship -- sort of. There's one caveat: in several key markets, the high-end iPhone 5s is not available for pre-order, only the iPhone 5c.

This naturally put investors on high alert that something might be amiss in the days before the 5s hits shelves. In the video below, Fool contributor Andrew Tonner breaks down the apparent problems facing the 5s supply and what it could mean for investors in the months to come.
