iPhone 4S features:

• Powerful Performance with A5 Chip:  Two cores in the A5 chip deliver up to two times more power and up to seven times faster graphics.² And you’ll feel the effects. Fast. iPhone 4S is quick and responsive, which makes all the difference when you’re launching apps, browsing the web, gaming, and doing just about everything. And no matter what you’re doing, you can keep on doing it. Because the A5 chip is so power-efficient, iPhone 4S has outstanding battery life.
• 8 MP phone camera: This 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. Not to mention an improved backside illumination sensor, excellent auto white balance, advanced color accuracy, face detection, and reduced motion blur. It all means that no matter how many people, how much light, and how much action you capture, everything looks exactly as it should. And just wait until you see the photos.
• 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.¹ It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.
• Video recording in 1080p incredible HD: Shoot stunning 1080p HD video everywhere you go. With all-new optics, the light is always right, the color is always vivid, and everything will look even better than you remember. Video stabilization steadies shaky shots. And you can edit video right on iPhone and share your lush life as fast as you shoot.
• The Most Advanced iOS 5: With every iOS advancement come even easier ways to do everything. That’s what makes iOS years ahead of anything else. iOS 5 leaps even further ahead, bringing over 200 new features to iPhone 4S.
• iCloud – To Manage Your Stuffs: iCloud 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. And it just works.
• Retina Display: The sharpest, most vibrant thing you’ll see on iPhone 4S is everything. The Retina display is the highest-resolution phone screen ever. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. But without a doubt, you’ll notice crisp text, sharp graphics, and stunning images. It’s more remarkable than the printed page. And you’ll be completely absorbed.
• FaceTime: FaceTime lets you hear a voice and see the face that goes with it — iPhone to iPhone, iPad 2, iPod touch, or Mac over Wi-Fi. So no matter where they are, no matter where you are, you’ll always be there. Making a FaceTime call is just as easy as making a phone call. And it’s even easier with Siri. Just tell Siri “FaceTime with Mom” and you show up, smile, and wave hello. You’ll never miss a big event, an important meeting, or a good laugh. And who wouldn’t be happy to see your face?
