Apple the worlds top brand. And iphone 4s is the device come under this brand. And mobile make you feel awesome but its features are not good. I say this mobile is only for showoff. Mobile disply and touch both are great. It make you feel different. Cameras are also not good. If you come to about bettery backup. Then it makes you feel wrost. Belive me I was using since 1 year. U have to always put on charger. If you about to buy it I say no to you. . Thankyou
