Sometimes, it has been seen that before the release of some awaited gadget, some other company may demand that it has been developing the product.

Just the same is now going on with leading gadget maker Apple. Apple sources have informed that the next generation iPhone was the brain child of it but it couldn't stop the technology enthusiast website Gizmodo. The website has claimed that the device has been designed for AT&T's GSM network.

So far as the features are concerned, the device is loaded with a front-facing video chat camera, an improved back-of-phone camera with flash, a larger battery, an improved display. It also has a Micro-SIM card, buttons for volume control and many more iPhone features.

For years, Apple has maintained a high level of secrecy of its best device control in all the industry and its prototypes. Despite tight security measures, Gizmodo has managed to get the detail, which means Apple's next-gen iPhone secret is no longer a secret.

However, the company has denied the fact and has issued a letter to the Gizmodo editorial director Brian Lam asking to return of the device.
