IPhone 4S: New Technology



It is like a passion of this new generations’ to have iPhone. Apple introduced iPhone in 2007 for first time. And it became most successful technology and the evidence of this is a line of thousands of customers to be the first to buy the phones, which featured computing and Wi-Fi capabilities, along with a crisp, computer-like display on an innovative touch screen.
It constantly and continuously improves it and make new version with special features. Following this principle in October 2011, the company revealed an excitedly awaited new version of the device, the iPhone 4S.  It is the fifth generation of the iPhone and retains the exterior design of its predecessor, the iPhone 4, but is host to a range of improved hardware specifications and software updates.
Some of the special feature make it more special and more demanded, the phone added a voice recognition system known as Siri, that recognized voice commands by users to schedule appointments, dictate text messages and conduct Web searches; and a cloud storage service named iCloud which is the easiest way to manage all your stuff, because it manages it all for you. iCloud stores your music, photos, apps, mail, contacts, calendars, documents, and more. And wirelessly pushes them to all your devices. It’s automatic, effortless, and seamless. The iSight camera just might be the best camera ever on a phone. And with all-new optics, it just might be the only camera you need. Because behind every shot, you’ve got 8-megapixel resolution and a custom lens with a larger f/2.4 aperture
Although the new phone was virtually indistinguishable on the outside from its predecessor, the iPhone 4, it was packed with better technical innards, including a more advanced camera. The phone also included a more powerful chip known as the A5, the same microprocessor that acts as the brains inside the iPad.
