As expected, Apple unveiled its new iPhone 4S at its media event this afternoon. It’s available for pre-order on October 7th, and will begin shipping on October 14th. Availability on the 14th will be restricted to the US, Canada, Australia, UK, France, Germany and Japan. Twenty two more countries will get the phone by the 28th, and 70 by the end of the year. The 4S will be available on Sprint, AT&T and Verizon networks in the US. Contrary to rumors that indicated a complete overhaul of the phone, the 4S is a predictable progression from the iPhone 4. It uses the same Apple A5 SoC as the iPad 2 (though, as usual, Apple didn’t reveal its clock speed or the amount of on-board RAM) and is now universally compatible with CDMA and GSM networks (making it a "world phone), but is visually similar to the iPhone 4 and uses the same 3.5” 640x960 “Retina Display” as its predecessor. It will be available in 16GB ($199), 32GB ($299), and 64GB ($399) capacities in both black and white with a 2-year contract. The iPhone 4 will remain as an 8GB phone for $99, while the 3GS will also stick around for free with contract. Antenna diversity, a feature originally introduced in the CDMA iPhone 4, is now standard on all models of the iPhone 4S. As we found in our review of the Verizon iPhone 4, antenna diversity fixes the infamous antenna issue with the iPhone 4's design. The wireless stack has been upgraded to support HSPA+ 14.4, likely courtesy of Qualcomm's MDM6600. As was widely predicted, the iPhone 4S sports a new 8MP camera sensor with a five element f2.4 lens. The new lens is apparently 30% sharper than the previous iteration. The camera subsystem itself supposedly has better color accuracy and more color uniformity. Apple talked about their custom designed Image Signal Processor (ISP) on the A5 SoC, however previous versions were also Apple designed. Apple claims 1.1 seconds to the first photo and 0.5 second shot-to-shot latency on the iPhone 4S. The camera can now shoot 1080p video due to the ISP upgrades in the A5 SoC. Wireless display mirroring via AirPlay is also supported on the iPhone 4S. The new iPhone will debut with iOS 5, which will also be available to users of older devices on October 12. Exclusive to the new iPhone is iOS 5’s Siri voice assistant, which promises to bring new precision and utility to voice commands on the phone. The iPhone 4S with Siri will be able to understand natural language requests (e.g. "Wake me up tomorrow at 6AM) and act accordingly (e.g. create an alarm for 6AM tomorrow).
Expect a full review from us as soon as possible, and in the meantime you can always re-read our in-depth iPhone 4 review to get a better idea of what has changed since last summer.
