Apple kicked off its annual iPhone refresh on Tuesday, introducing the iPhone 4S. This newest handset sprinkles in many powerful features, including voice commands, a better camera, and "world phone" antennas – things that will keep the iPhone line chugging along at full speed. However, Apple used Tuesday's keynote as a chance to catch up with the competition, not as a moment to zoom past its biggest rival, Android.
The iPhone 4S enjoys the speed and power of Apple's A5 chip, the same processor inside the iPad 2. This faster dual-core engine handles graphics seven times faster than the iPhone 4, a boon for high-resolution apps. Its new camera jumps from 5 megapixels to 8. And unlike the older model, which required shoppers to choose between a GSM or CDMA antenna, the iPhone 4S is a "world phone." That means the same device can hop between Verizon, AT&T, Sprint, or nearly any network overseas.
This new antenna should improve call quality as well, says Apple. While the iPhone 4 has a history of dropping calls – remember "the death grip"? – the company says this new design allows the iPhone 4S to switch between its multiple antennas on the fly, improving call quality and data speeds.
