iPhone 5S, 5C and iOS 7 Announcements Coming Today at Apple's Campus

After months of rumors and speculation, Apple is set to announce today its next iPhone or iPhones – the iPhone 5S and the iPhone 5C. Starting at 10 a.m. PT / 1 p.m. ET, Apple's CEO Tim Cook is expected to take the stage at Apple's campus in Cupertino, Calif., and detail the new features of the phones as well as announce the release date of iOS 7, the next version of the iPhone and iPad software.

Thanks to months of leaked images and rumors (which we gathered together here) we have an idea of what Cook and his team might just reveal.

The iPhone 5S is going to be a lot like the other S versions of the phone (iPhone 3GS, 4S) -- similar to the iPhone 5 but with some new tweaks. The biggest addition is said to be a fingerprint sensor in the home button of the phone. The sensor would allow users to quickly sign into the phone without having to put in a PIN or password. Other than that, the phone is said to look very similar to the iPhone 5, though it is said to come in a new champagne or gold color. A faster processor and improved camera flash are said to also be added to the 5S.

Expected to join the 5S is a cheaper, plastic version of the iPhone -- the iPhone 5C. According to the numerous leaked images, the phone will come in a selection of colors -- thus the "C" -- including pink, white, blue and green. The phone will be cheaper than the 5S and could replace the iPhone 5 or 4S. Apple usually drops the price on its older models when newer ones are introduced.

When it comes to the software, the new iPhones will run Apple's iOS 7, which the company detailed in June at its Worldwide Developers Conference. iOS 7 is the biggest change the software has seen since the original iPhone was introduced in 2007. It has an entirely new design, including revamped icons and animations, and a host of new features, including a new Command Center for easy access to settings, a new multitasking view and revamped Camera, Mail and Calendar apps.

According to ABC News' sources, the iPhone 5S and 5C will go on sale at Apple Stores on Friday, Sept. 20. The iOS 7 software will likely be released around the same time and will be available for the iPhone 4, 4S and 5 via a download.
