The iPhone 4 is a touchscreen smartphone developed by Apple. It is the fourth generation of iPhone, and successor to the iPhone 3GS. It is particularly marketed for video calling (marketed by Apple as FaceTime), consumption of media such as books and periodicals, movies, music, and games, and for general web and e-mail access. It was announced on June 7, 2010, at the WWDC 2010 held at the Moscone Center, San Francisco, and was released on June 24, 2010, in the United States, the United Kingdom, France, Germany and Japan.

A new report released today by Bloomberg is strengthening rumors that Apple is prepping an upgraded model of its iPhone 4 handset for launch in September. According to the report, the next-generation iPhone will be getting the dual-core A5 processor that currently powers the iPad 2, as well as a new 8 megapixel rear camera.

While the processor upgrade has been considered a given – Apple made the same move with the A4 chip, launching it in the iPad and then bringing it to the iPhone 4 – there has been quite a bit of speculation as to whether or not the rear camera would be seeing any change at all. Apple’s current 5 megapixel lens has stood up well over the past year, and continues to be one of the better phone cameras available. It appears with today’s report that Cupertino is leaning towards a higher resolution shooter for the next iPhone.
