Apple is good brand of the other brand. In one year ago I purchase iphone 4s. to reason is good brand and no hanging problem. To provide good specification, camera, and other feature is good. Iphone design is good and the also good for internal specs. Battery life for the iPhone 4S is estimated at up to eight hours of talk time and 200 hours of standby time.
it is good sound in the phone.and also good for the easy to use on the mobile.
It is pros for advanced operating system give this smartphone capabilities that have never before been possible.
It is good value for money.
