Waiting for the new Apple iPhone? Mark your calendar for Sept. 10.

The new Apple iPhone, which reports say will be called the iPhone 5S, is expected to be introduced on Sept. 10 and put on sale a few weeks after that. 

Autumn: A season of falling leaves, pumpkin-flavored coffee beverages, and new Apple iPhones. 

According to a new report from Ina Fried of All Things D, the next generation of Apple's bestselling smart phone will almost certainly be unveiled at a big press event on Sept. 10, in California. Apple, of course, isn't confirming the gossip, or even answering questions about it, but the timing lines up: The last iPhone – the iPhone 5 – was unveiled almost exactly a year ago, on Sept. 13, 2012. 

So what will this new iPhone look like?

Well, signs point to a device that maintains the same sort of relationship to the iPhone 5 as the iPhone 4S did to the iPhone 4. In other words, we very much doubt we'll be looking at a massive aesthetic overhaul. Instead, the iPhone 5S (our educated guess on the name of the thing) will likely use the same frame as the iPhone 5, but include upgraded innards, such as a faster processor and better camera and flash. 

There's also been a lot of talk about a biometric scanner, a next-gen feature that would read the fingerprints of the user; and a concave home button with sapphire touches.

At any rate, the iPhone 5S will definitely run iOS 7, the already-announced successor to the iOS 6 operating system that powers the iPhone 5. 

Apple sold five million iPhone 5 units in the first weekend after launch – a tremendously impressive number. And yet because analysts had forecasted first weekend numbers of as many as 10 million units, the launch was greeted in some quarters as a "disappointment."
