Ever since Apple released the first iPhone in 2007, it has quickly grown to become popular smartphone on the U.S market. The one thing which made the iPhone stand out from the competition was the fact that it was the first multi-touch capacitive touchscreen smartphone to ever be released. And since the the first iteration of the iPhone, the market for capacitive touchscreen smartphones has grown enormously. Many competitors including HTC, RIM, Palm, Samsung, Motorola and more have since released products which would rival the iPhone. Apple knew that in order to remain on top, they had to make the fourth iteration of their hot selling smartphone much improved, and they did just that with the iPhone 4.

The Apple iPhone 4 features the same powerful 1GHz A4 processor found on the iPad, a beautiful 3.5" display with a 960x640 resolution, the highest resolution found on any smartphone on the market, a front facing camera for video calls (as well as FaceTime, their own videoconferencing software), and a 5MP camera with flash capable of recording video up to a resolution of 720p. The powerful processor along with the gorgeous display and the smoothness of Apple's smartphone operating system, iOS is what makes the iPhone 4 deliver a positive user experience.

One thing about the iPhone is that due to the popularity and how advanced the device is, the resale value tends to hold very well. Whenever an iPhone 4 user will be ready to upgrade to their next phone, they should be able to sell their iPhone 4 and use that money to pay for their next phone (with 2-year contract), perhaps even a future iteration of the iPhone. But in order to maximize the resale value of the phone, the smartest thing to do is to purchase a case in order to keep it in like new condition.

As somebody who has used many smartphones and tested many cases, there is no brand which I prefer over Otterbox. The quality of their cases can be seen by how durable they are along with the great feel of the case and innovative designs. This particular Otterbox case is a part of their impact lineup which offers extra layers of protection and is built to be a great heavy duty yet stylish case.

This case can offer maximum protection for your phone from potential scratches, scuffs, dust, bumps, cracks and minor falls. This case is custom designed for the iPhone 4 and includes easy access to all ports, buttons and cameras. This case also offers a textured skin for outstanding grip. And it is available in various designs including a red heart, teal lion, orange floral, green floral, pink hummingbird, blue wheat floral, black skull, black lines and purple circled lines. If you are looking the best protection for your powerful smartphone, then look no further than this Otterbox impact case.
