First there’s that name: It’s the old phone’s name with an S attached to it. As the iPhone 3GS taught us, adding an S to an iPhone’s name can represent numerous under-the-hood improvements, but it doesn’t send shivers down your spine like incrementing a number by one and unveiling a redesigned exterior with mind-blowing features that may or may not include anti-gravity.
The results of my general-performance tests showed the iPhone 4S to be roughly twice as fast as the iPhone 4.
Apple’s never going to win a competition with the wildest imaginations of tech bloggers. But the company seems to be doing OK in the business of building phones. The iPhone 4, which remained more or less unchanged for 15 months as approximately a zillion Android smartphone models came and went, has consistently been the best-selling smartphone around (at least in the U.S. and Europe).
Now here comes the iPhone 4S, which is more of a good thing: It takes the successful look of the iPhone 4 and tosses in a dual-core processor for dramatically improved speed, an upgraded camera, and some brand-new voice-command technologies.
Feels like an iPhone
It’s a classic look, easily my favorite of all the iPhone designs to date. The fit and finish are immaculate; not a single thing about the iPhone 4S feels cheap. In terms of styling, the iPhone 4 feels like the most expensive electric razor ever made, or maybe like a finely-tuned luxury watch. The same eye-popping 960-by-640-pixel screen introduced with the iPhone 4 is present on the iPhone 4S, too. Dubbed the “Retina display” by Apple, it’s got a screen resolution of 326 pixels per inch, meaning that the average human eye can’t even see individual pixels. The result is marvelous. Reading text is like looking at a printed page. High-definition videos and photos display tiny details.
With the exception of a micro-SIM card slot on the right side, the iPhone 4S is a dead ringer for the CDMA version of the iPhone 4 introduced in February in the U.S. by Verizon. Extremely precise cases designed specifically for the original iPhone 4 may have trouble fitting over the ring/silent switch and the volume buttons of the iPhone 4S, which are slightly shifted from their position on the GSM iPhone 4; precision cases for the CDMA iPhone 4 and less-precise iPhone 4 cases will have no trouble.
On the front of the phone there’s a VGA-quality camera (640x480 pixels) that’s designed to be used for video chatting, either via Apple’s FaceTime technology or via a third-party app such as Skype or Google+. This, too, is unchanged from the specs of the iPhone 4.
In essence, only a Sherlockian attention to detail would allow you to differentiate between the GSM iPhone 4, CDMA iPhone 4, and the iPhone 4S. (Budding detectives: The symmetrical black lines on both sides of the phone are the sign it’s not a GSM iPhone 4; if there’s no micro-SIM slot on the right side, it’s the CDMA iPhone 4; if the lines are symmetrical but the slot is there, it’s the iPhone 4S.)

This does not mean that the iPhone 4S is essentially the iPhone 4 with the benefit of an extra letter. Because on the inside, the iPhone 4S is dramatically different from the iPhone 4.
