We all know that the upgraded iPhone 5 is just around the corner and a leaked internal document from a Japanese carrier reveals that the next generation iPhone will be announced on June 20 and will be available in the stores by July.

The leaked document also suggests that the iPhone 5S (as it is referred to in the document) will run on the upcoming iOS 7 operating system and that the camera on the back has been upgraded to 13 megapixels from the 8 megapixel unit on the iPhone 5.
The Apple iPhone 5S is rumored (http://www.gsmarena.com/iphone_5s_rumored_to_feature_front_camera_dualshot_support_-news-5942.php) to have a 2 megapixel front shooter with the ability to record full HD videos. The device is also said to have dual-shot functionality in camera, currently seen on LG and Samsung phones but a first for an iPhone.
The reliability and the accuracy of the document are in question, so we suggest you take this information with a pinch of salt.
