It's official. Apple will announce the supposed iPhone 5S release date and reveal the new product at a special event on September 10.

The company sent out invitations today for the announcement event which will take place in Cupertino, Calif. The company sent out media invitations which reads "This should brighten everyone's day." The text is surrounded with colorful dots, which may reflect Apple's upcoming colorful iOS 7 or it could be a hint at the color options for the rumored cheap version of the iPhone, the iPhone 5C.

Nothing is confirmed yet, but chances are good that Apple will be announcing the latest iPhone. Rumors says that there will be two products announced this time including the iPhone 5S, an update to the iPhone 4, and the iPhone 5C, which is a low-cost version.

Among the rumors are that the iPhone 5S will have the same design as the iPhone 5, but it will come with a new fingerprint sensor embedded near the circular home button. This would give the phone added security. Additionally, the new iPhone is expected to have a faster processor, improved camera and may be available in a new champagne or gold color.

The low-cost iPhone 5C is said to come in a selection of bright colors such as blue, green and yellow and will be made of plastic. It is believed that this product will replace the current iPhone 4 or 4S which are cheaper. The new phone is not expected to have the large screen that the iPhone 5 has.

Something that is confirmed is that the new iPhone will run on iOS 7. The new operating system looks very different from previous versions as it has new designs and features, including a Control Center with easy access to settings from any screen and new multitasking features. It is common for Apple to introduce a new operating system around the time that they drop a new product. It will also be available on the iPhone 4, 4S and 5 and the iPad 2, iPad with Retina and the iPad Mini.

The release event will be on September 10 and 10 a.m. It is not clear if Apple will stream the event live. It is expected that Apple will release the new product on September 20.
