iPhone 5 to Use a 4-Inch Screen

Rumors say that Apple might expand the next generation iPhone’s screen to 4 inches to better compete with Google Android.

The component suppliers noted that the production lines for Apple's next generation iPhone have begun testing, and Apple is interesting in expanding the screen size to 4-inches to support the tablet PC market as the vendor only has a 9.7-inch iPad in the market.

Though, Apple’s prototypes for testing usually have little bit different designs than real products.
