Speculations have been doing the rounds on the release date of Apple's next generation smartphone iPhone 5. It was reported that the company would unveil it by the end of the year, but now we heard that it will hit the stores in September.

Apple is planning to debut the new iPhone at a special event on Wednesday, September 12, 2012, with the release date to follow 9 days later on September 21, reported iMore website claiming that it got the information from a reliable source.

Apple has not made any official announcement on its much-awaited iPhone but rumours and speculations around it keep coming. Even several of the iPhone 5 engineering sample photos have made its way to the net.

Claiming that a trusted source inside the Apple supply chain in China gave the information, tech site GottaBeMobile carried on its page the metal iPhone 5 design sample.

iPhone 5 is slightly taller and slimmer than its predecessor iPhone 4 thought the width is the same, reported GottaBeMobile. According to the site, iPhone 5 is 120mm tall compared iPhone 4S' 115.2mm, which means it has bigger screen display.

The upcoming iPhone reportedly has a 4-inch edge-to-edge display according to MyDrivers website. The engineering sample doesn't show a metal back though rumours have it that iPhone 5 would come with one.

Apple is yet to issue an official announcement on the upcoming device, but a source close to Foxconn, which assembles iPhone and other Apple products, had earlier claimed that iPhone 5 would put Samsung Galaxy S3 to shame.

"Consumers should wait for the iPhone 5 because it will put the Samsung Galaxy S III to shame," Focus Taiwan quoted Foxconn CEO Terry Gou as saying in China Times. "With (Foxconn's) marketing and manufacturing strengths and Sharp's key technologies, the two will be able to defeat their arch-rival Samsung," the report added.

According to rumours, iPhone 5 will feature a 4-inch Retina display, an A5X Variant chip, 1GB RAM, iOS 6, 4G LTE technology, Near Field Communication (NFC) technology, improved Siri, liquidmetal casing, an 8 megapixel (or even higher) rear camera, a 2 megapixel front-facing camera for video chatting and a much-improved battery life.
