The iphone 4S  specs and features have now been explained. The 4S will feature Apple’s A5 chip, used in the iPad 2. Mike Capps, the president of Epic Games got on stage and ran a quick demo of a game with the iPhone 4S. The CPU on the iPhone 4S has a 2x faster CPU and dual core graphics. Eight hours of 3G talk time. Nine hours of wi-fi browsing. Ten hours of video. The new phone can switch between the two antennas to improve the call quality, and can download data twice as fast. In general, though, the antenna appears to still be wrapped around the outside of the device. The iPhone 4S is a world phone, and will work on both GSM and CDMA networks. The new camera has an 8 megapixel sensor. That’s 3264 x 2448 for you pixel counters out there. That means you can print out an 8 x 10 photo while the new sensor is 33% faster, said Schiller. The new iPhone will record 1080p HD video, and includes image stabilization features.

Airplay is Apple’s system for streaming media to different devices, such as AppleTV. The iPhone 4S, like the iPad 2, will have “Airplay Mirroring,” which allows you to show exactly what you’re seeing on the phone screen on a big-screen TV via an Apple TV. They are showcasing their voice activated software for the phone called Siri. Forstall presses and holds the home button on the iPhone and asks his phone what the weather will be like, and it pop ups up the weather. He then asked it “Do I need a raincoat today?” Siri answers: “It sure looks like rain today.” He shows how he can ask Siri to “wake me up at 6 a.m.” and the phone sets an alarm for 6 a.m. Siri uses a familiar computer-generated voice that sounds like a slightly drunk Swedish person speaking English. For users in cars, Siri can send and read messages so that users don’t have to handle the phone. Now he asks: “Who are you.” Siri’s answer: “I am a humble personal assistant.  Siri also does dictation, he said. So anywhere an application might normally show a keyboard there is now a microphone, where Siri will type for you. It will launch in Beta with support for English, French and German. The prices are $199 for 16GB, $299 for 32GB and $399 64GB, with a two-year contract. Pre-orders start on Oct. 7, and the phones will be available on Oct. 14. The iPhone will be available on Sprint for the first, time, he said. By the end of the year, it will be available in 70 countries, with 100 carriers — “the fasted rollout we’ve ever had,” he said.
