It is not surprising that Apple's iPhone 4 ranked No.1 due to its intense popularity which spurred record sales numbers. Powered by the iOS 4 mobile operating system, the newest incarnation of the iPhone has a built-in A4 processor and a PowerVR SGX53 graphics engine that increase speeds and make transmitting 720p hi-def videos a breeze.

The "Retina Display" screen itself makes everything on the phone amazing. The 3.5 inch, 960x460 high resolution IPS touch screen can achieve a wider viewing angle than the typical LCDs, meaning one can hold the iPhone 4 in almost any way without losing its brilliant picture.

As a smart phone, the iPhone 4 contains all the functions one needs in a mobile device; text messaging, visual voicemail, portable media player, an Internet client, email, web browsing and Wi-Fi connectivity. The iPhone 4 also comes equipped with two cameras for the product's unique high-resolution "FaceTime" video calling system.
