Description
The iPhone 4s is a gradual step over the iPhone 4 improving the internals, but keeping the look and feel. At the same time, though, it brings a reworked iOS 5 and introduces Siri, a personal voice assistant allowing you to vocally communicate with the iPhone. It comes with a 3.5' screen with a resolution of 640 x 960 pixels, but on the inside there's a twice more powerful dual-core A5 processor. It also improves connectivity a notch, bringing 14.4Mbps HSPA download speeds. The back is where an 8-megapixel camera resides and it's capable of recording 1080p videos.

The iPhone 4 is now boxier, with the rear side now flat, instead of rounded. It will keep the 3.5-inch display diagonal, but will quadruple the pixels to 640x960, making it the highest-resolution screen on a smartphone to date. Apple actually calls the new screen Retina Display, because it shows 326 pixels per inch, while the human eye can only distinguish around 300 ppi. In addition, the screen will utilize the LCD IPS technology (same as in the iPad). The other new stuff includes a front-facing video call camera, 5MP main camera lens with LED flash and 720p HD video recording, Micro-SIM slot, instead of ordinary SIM, a secondary mic for noise-cancellation and a lot of other new features.
