I have been using iPhone since a long time now. iPhone 4s was my first smart phone.Being a iOS developer I need a device for testing.
Although there are several more iPhone have come in market since iPhone 4s, its still one of the best devices out there.
The best feature of buying an iPhone is that you can update to the latest iOS available(till date) which is not the case with most of the android devices. Even after upgrading the iOS the device run well.
iPhone 4s is really durable. Its strong, durable and handy.
A good choice for a small screen smart phone.
