Riding off the iPhone 3GS of 2009 that is still selling well to this date, the iPhone 4 stepped up Apple's flagship smartphone a notch further by introducing the Retina Display. Sporting an all-time high screen resolution of 960x540 pixels that yields an image quality of 326ppi, this record still remains unbeaten on any other smartphone, or tablet, for that matter. Hence its name, the screen resolution is supposed to be so sharp that the retinas in our eyes would not be able to discern any individual pixels. Indeed, this promise is fulfilled as the display is indeed crystal clear and sharp at this resolution, with text and fonts appearing as good as print, while graphics, web pages, and photos truly do come to life on its 3.5-inch touchscreen. With a resolution that good, it likely came as no surprise that its successor the iPhone 4S still sports the same resolution, since it is doubtful as to how much more can it be improved further, or if it is even worth improving at all in the first place, since probably our eyes would not be able to tell the difference!
With the same 3.5-inch touchscreen as its predecessor the iPhone 3GS, the iPhone 4 is beefed up with a speedier A4 processor running at 1GHz coupled with 512 MB RAM. Although both the iPhone 3GS and iPhone 4 support the latest iOS 5 released by Apple, it is basically the upgrade in speed and specs in moving from the iPhone 3GS to the iPhone 4 that is truly a huge step ahead in terms of sheer performance despite having the same core functionality. This basically means that while the iPhone 3GS can pretty much do everything that the iPhone 4 can, but the iPhone 4 certainly does it so much better, with a sharper display, and an even faster and smoother slick experience that is the trademark of Apple's iOS.
With an upgraded camera to 5 megapixels that can now shoot videos at HD 720p resolution, this certainly completes the entire suite of feature upgrades that has made the iPhone 4 a game changer since its release in 2010. Since then, practically all its key competitors, from Samsung's Galaxy S2 to HTC's Sensation and so on were designed quickly in 2011 in response to the iPhone 4. While some of these other top guns could have edged out the iPhone 4 in a spec or two (to which Apple responded with the iPhone 4S), the fact still remains that no other smartphone to date can match the slickness and ease of use of Apple's iOS 5 running on the iPhone 4, if not the iPhone 4S. Although now in second place behind its successor the iPhone 4S, the reality is that the iPhone 4S features were only enhanced further from the iPhone 4, with an A5 processor, voice recognition, an 8MP camera and a 1080p camcorder.
The iPhone 4 form factor still remains in its 4S successor to date, which likely proves Apple's desire to preserve what is desirable to its users. Though the 3.5-inch touchscreen might seem a tad small if compared to some of the popular 4-5 inch displays by Samsung and HTC, size is a subjective trade off between screen visibility versus portability. The iPhone 4 that was reshaped into a more rectangular slate and with a polished metal frame for its edges has certainly packed the right premium feel for the iPhone 4 to be ever as desirable to this date, and which has certainly set the benchmark for more smartphones to come.
