I purchased it last year from a shop. The iphone 4s is a good looking piece of kit. It still looks and feels expensive, and, while it is thicker than other iphone. The iphone 4s weight is 140 grams. The iphone 4s has a 3.5in display. I find that the smaller display means the iphone 4s firs in my pocket nicely, and is easy to carry arround. The iphone 4s has complete glass back. It's display is 960 by 640 pixel, with a screen resolution of 326 pixel per inch, making it Retina standard. The rear facing camera in the iphone 4s is an 8 megapixel iSight camera. It has an f/2.4 aperture and can shoot 1080p viseo. It is has a dual core A5 processor.
