The announcement of the Apple iPhone 4 in 2010 ushered in a new era for the design of the iPhone. Whereas previous versions featured a curved shape, the iPhone 4 features a boxy shape that allows owners to stand the phones up horizontally and vertically.

Apple suffered a public relations mishap soon after the iPhone 4 was released when users began to notice that the iPhone 4 dropped calls when they placed a finger or a hand under the bottom left corner of the device. For a time, Apple offered free bumpers to any person who bought an iPhone 4. Apple no longer offers the free bumpers, but the iPhone 4 is still prone to the same problems.

Given that you probably paid a significant amount for your Phone 4, you should use iPhone 4 cases to protect your investment. The iPhone 4 features several features that allow you to be productive and efficient, however if your iPhone is damaged, your productivity will certainly decrease. Some of the top iPhone 4 features include:

Retina Display

The iPhone 4 was the first iPhone that Apple promoted as having “Retina Display.” The term is based on the fact that a human retina is able to perceive no more than 300 pixels per inch at a distance of 12 inches. The iPhone 4 features 326 pixels per inch. Apple claims that the iPhone 4 resolution is technically perfect because a person cannot pick out any individual pixels on the display.

Because of the high-resolution screen on the iPhone 4, it is vital that you protect your screen with one of the iPhone 4 cases on Cases.com that is designed to keep the screen from becoming cracked, chipped, scratched or otherwise damaged. You can find handmade soft leather pouches on Cases.com that are designed to protect your iPhone from elements that may damage it.

iPhone 4 Camera

A dual camera feature was one of the new features that Apple included on the iPhone 4 when it was released. Previous versions had one outward-facing camera. The iPhone 4 featured an inward-facing camera as well. One of the main uses for this camera is the FaceTime function, which allowed iPhone 4 users on a Wi-Fi network to connect with other iPhone 4 users .More-recent updates now allow iPhone users to connect to FaceTime users on MacBooks and iPads as well.

Of course, if you cannot see the photos you take because of a damaged screen, the 5-megapixel camera and FaceTime are rendered much less effective. Cases.com features a number of iPhone 4 cases made from imported leather that feature a magnetic flip closure as well as a removable belt clip.

iPhone 4 Multitasking

Although previous versions of the iPhone featured thousands of downloadable apps and built-in functions, the iPhone 4 was the first iPhone to allow users to have apps open in the background. This means an iPhone user can do things such as listen to Internet radio while simultaneously updating his Twitter or Facebook account.

Cases.com features several formfitting iPhone 4 cases that allow you to have quick and easy access to your iPhone while you seamlessly moving from one app to the next.
