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.
