Informr score
The Apple iPhone 4 currently has an Informr score of 8.3 out of 10. This score is based on our evaluation of 42 sources including reviews from users and the web's most trusted critics.

The Apple iPhone 4 came onto the cell phone scene in 2010. When the iPhone 4 was introduced, the improved physical design was immediately evident, and the list of updates was impressive.

To begin with, the iPhone 4 has a more stylish and hi-tech look than the earlier iPhone models. Both the front screen and back panel are constructed with super strong aluminosilicate glass, the same glass used for windows on helicopters. A band of brushed stainless steel that wraps all around the phone is the antenna.

The iPhone 4 comes with a 5 megapixel camera on both the front and the back, no more shooting photos of yourself in front of a mirror, the camera easily switches from front screen to back screen view. With added 5x digital zoom, and a flash that can be turned off, this is one of the best phone cameras on the market today.

The video recording is now HD, and combined with Apple's iMovie or another app, high quality videos are at your fingertips. Another feature of the front screen and back screen camera option is Face Time, video conferencing that is as easy as making a phone call.

At the basis of all these improvements is Apple's move to the powerful and energy-efficient Apple A4 chip. The new IOS 4, which Apple calls "the most advanced mobile operating system in the world" brings with it several upgrades. These include multi-tasking, which, when combined with the faster app switching, makes every application on the iPhone easier to use. The added gyroscope feature offers all way motion sensors- the best thing in the world for gaming. iPhone 4 comes with folder options that are easily organized, re-organized and updated. Enhanced mail features along with many other features, big and small are included.

Saving the most awesome improvement for last, we come to the Retina Display. This updated display is super bright, crisp and completely pixel free. With 326 pixels per inch, the human eye is not capable of distinguishing pixels from any angle. The contrast is at a whopping 800:1 ratio, four times higher than previous iPhones.

This is the world's best selling smart phone for a reason.

At a hefty cost, the Virgin Mobile iPhone 4 delivers an unlimited plan without a contract -- just don't expect blazing-fast data speeds.Other than pricing, data speeds, and call quality, Virgin's iPhone 4 is pretty much the same as all the others.

Every iPhone elicits strong reactions from the fanboys on one side and the detractors on the other.

In-spite of being a year late, the iPhone provides a sublime smartphone experience. On paper, one would think that the likes of the Samsung Galaxy S 2 and LG Optimus 2x would walk all over it due to their superior hardware but that was clearly not true. The iPhone matched them punch for punch and in...

That cost was not factored into the price of our test unit.After our testing, the question we were left with is...
