Will work on AT&amp;T. 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. 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. 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. 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. </p> <p class="product-promo-text"><span class="product-promo-header">FREE US shipping over $100!</span><span class="product-promo-body">Orders within next 2 days will be shipped on Monday</span></p> 509.99000000 235M 54 CS-Cart apple-iphone-4s-white 166/234/235 B 3.00 1
