Apple's iPhone 4, despite the early design issues, has followed the same trend as the earlier iPhones and become a huge success. The iPhone is no longer used exclusively by Apple fans but has been embraced by a wide range of people. Indeed, due to its versatility the iPhone is fast becoming the default phone used by modern businesses across the world. Sprung up around the iPhone is another flourishing and important market; iPhone Cases.

The iPhone 4 is encased front and back by thin glass screens. These screens, whilst designed to be scratch resistant have, on occasion, cracked or shattered leaving the phone useless to its user. Shattered screens have predominately been the result of dropping the phone for whilst the glass might be scratch resistant they are not shock resistant. The sudden shock of dropping the phone onto a hard surface sends shock waves through the glass plates and for the unlucky ones this results in cracks. A properly designed and made iPhone 4 case will help to absorb the shock waves, transmitting the destructive energy around the phone and away from the delicate glass plates leaving the iPhone intact and useable.

When selecting a case for your phone pick one that has been designed to protect your iPhone and is not just a cheap fashion accessory. A cheap iPhone 4 case will offer very little protection and the chances are you will still damage the glass screen when you drop your phone. Another sensible choice is to purchase a screen protector kit that has been designed for the iPhone 4. These kits come with protective film that has been designed to fit on both glass plates, and some of the more high quality kits also offer protective film for the sides of the iPhone as well!

There is no doubt that the iPhone 4 is a modern marvel but like everything it does have its weaknesses. In the case of the iPhone 4 its weakness is its glass screens. If not suitably protected these screens can be easily damaged if your iPhone is dropped. Don't take the risk, spend a few more dollars and get yourself an iPhone 4 case. You won't be sorry!
