iPhone 4S fills in many of the holes that left Apple's line vulnerable to the competition. However, the iPhone 4S adds few truly new features.
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.
