ive had every iphone up till the 4. I dont need a 4s as im not fussed with siri, dont really use the camera as i have an SLR cam, however it is slightly faster than the ip4.iPhone 5 ? hmmmm i like the big screen and the speed but read reviews and also said on the gadget show that battery life is not as good as the 4/4s. also price will be high.Not sure on the android market but perhaps look up the Samsung S3
