Apple iPhone 4 Technical Specifications

Hello there, this post is my favorite one as this is all about my favorite gadget- The Apple iPhone 4. Yes, this is my favorite phone and i know it's your's too and if not, then don't worry it will be. After reading it's Technical Specifications, i bet anyone will become it's fan. Well i am already a big fan of the Apple Inc. and all of their gadgets from iPod to MacBook.

Apple iPhone comes with a bunch of awesome features like Retina Display- It is the sharpest, most vibrant, highest-resolution phone screen ever, with four times the pixel count of previous iPhone models. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. Which makes text amazingly crisp and images stunningly sharp.

Apple iPhone 4 also comes with two cameras: One on the front, which focuses on you. And one on the back, which focuses on everything else. FaceTime lets you switch back and forth between them at any time during a video call. All you have to do is tap a button.
