There are many reasons to purchase an unlocked iPhone 4, not the least of which is the newest feature: Retina Display. Hold up an iPhone 4 to any other iPhone and you will see a marked improvement in the quality of the screen. In fact, the pixels themselves on the iPhone 4 cannot be seen by the naked eye; that is how superior the Retina Display is. Hence, the sleek and crisp imagines on the iPhone 4 no matter what you are viewing.
Normally used in t.v. and computer monitors, this is the first time that such technology has been used in phones. It's pretty amazing that the developers of the iPhone 4 were able to cram 400% more pixels (which are now only 78 micrometers in length) into the screen without having to enlarge the screen itself. That means you are receiving a much sharper image due to the almost 330 pixels per inch on the iPhone 4. You will get crisp, realistic pictures because of the Retina Display.
Amazing Videos and Movies at Your Fingertips
Watching the videos and movies you have downloaded will be a whole new experience thanks to the Retina Display and the apps like Netflix. You will not lose any of the beauty of the images regardless of the angle because iPhone 4 has the in-plane switching ability and 8 bit color (as opposed to the normal 6 bit color technology). iPhone 4 is superior to its predecessors because the Retina Display contains a contrast ratio that is four times better.
Another advancement that Apple can boast about is the fact that the same material that is used in trains and helicopters is used for the iPhone 4 unlocked screen. This means that you will receive better scratch protection and a longer life from your screen than any other model phone you've ever owned. As an added protection, the screen is coated with a special material that doesn't attract oils and therefore finger smudges and keeps it cleaner than ever.
You are definitely getting a vastly improved viewing experience with the incredible Retina Display on the iPhone 4. Now, no matter what is on the screen, whether it's a movie, someone's blog or a digital photo, you will get a vivid and clear screen to view it upon as if it were a high end television or PC monitor. The Retina Display technology makes owning the iPhone 4 nearly irresistible. In plane switching (or IPS) technology and Retina Display in and of themselves make purchasing the iPhone 4 worth every penny.
