The newest i Phone 4S currently on the market, released in 14 October 2011.

Some of the exciting and electrifying features which make iPhone4s considerably exceptional from the earlier launched iPhones are mention below. · Siri: Now you can use your voice to use your iPhone. Just talk to Siri as you would to a person: “Do I need an umbrella?” or “Any great burgers around here?” or “Where’s the closest ATM?” Siri not only understands what you say, it knows what you mean. It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. · Dual-Core A5 Chip: Two cores in the A5 chip deliver up to two times more power and up to seven times faster graphics. · 8MP Camera: behind every shot, you’ve got 8-megapixel resolution and a custom lens with a larger f/2.4 aperture. · HD Video Recording: Shoot stunning 1080p HD video everywhere you go.
