Apple Store app now fills entire 4-inch screen of the iPhone 5.

Apple optimized the Apple Store app for the iPhone 5 over the weekend. The new version now utilizes the full 4 inches of the iPhone 5's screen, consequently taking advantage of the 16:9 aspect ratio.
While the device's taller screen has received praise, apps not yet optimized for the iPhone 5 appear in the older 3.5-inch format through a 4:3 aspect ratio. Such apps running on the iPhone 5 features black bars on the top and bottom of the screen.
The Apple Store app gives mobile users the opportunity to purchase products such as iPhones, iPads, Macs, as well as a batch of accessories. In addition, consumers can purchase items through the app and have it sent to their home or to their nearest Apple retail store for pickup.
