IPHONE 3GS REVIEW
In the face of the stepped-up competition, it’s possible to consider Apple’s new iPhone 3GS a minor step forward for Apple. After all, it looks almost identical
to its predecessor, which itself offered very few changes from the original iPhone model. But with the iPhone 3GS, combined with the iPhone OS 3.0 Software
Update, Apple has addressed all of its product’s key weaknesses while adding several important new strengths.

Yes, the competition is much closer to Apple now than it was two years ago. But the iPhone 3GS makes it clear: Apple is still leading the pack, in most cases
by a wide margin.

The S is for “same”
Externally, Apple hasn’t messed with success—the iPhone 3GS is almost completely indistinguishable from the original iPhone 3G model, which itself was
remarkably similar to the original iPhone. Front and center is the iPhone’s signature feature: a bright, beautiful high-resolution 3.5-inch diagonal touchscreen,
offering a resolution of 480-by-320 pixels. The iPhone 3GS has Apple’s usual complement of four physical buttons (Home just below the touchscreen,
sleep/wake up top, a volume up/down rocker on the left side, and a ringer toggle just above the volume controls) and the same black or white plastic back
shell introduced with the iPhone 3G.

If you need to know which model is which, there’s only one clear way to do so: Look at the lettering on the back of the phone. If it’s in the same silver ink as
the Apple logo, it’s an iPhone 3GS. (Likewise, if 32GB appears below the word iPhone, you know it’s an iPhone 3GS—the previous model was only
available in 8 GB and 16 GB editions, while this phone’s capacities have doubled to an impressive 16 GB and 32 GB, allowing users to load their phones up
with even more apps, tunes, and videos.)

Beyond the color-matched lettering, which shows a uniquely Apple-like attention to detail, the only other change to the outside of the device is the addition of
an oleophobic coating to the device’s touchscreen. When Apple designed the iPhone to be controlled entirely by touch, the company has had to deal with the
unpleasant reality that human beings tend to secrete oil from their pores, as well as stick their fingers in greasy foodstuffs from time to time. The iPhone 3GS’s
screen coating is intended to keep fingerprints to a minimum.

I’ve never really found fingerprints to be a major problem with the iPhone, since the device’s screen has always been quite bright. But it’s undeniable that in the
right lighting conditions, fingerprints can really get in the way—especially when you’re trying to watch a video.

The iPhone 3Gs’s oleophobic coating doesn’t make your fingerprints magically fade away. What it does is create an oil-repellant surface that’s easily wiped
clean. When I handled an iPhone 3G and an iPhone 3GS with similarly oily hands—olive oil, if you must know, from a pizza I was making—I was rapidly able
to dump my grubby prints all over both devices’ touchscreens. After I rubbed the iPhone 3GS screen onto my t-shirt’s right sleeve, it was perfectly clear. In
contrast, rubbing the iPhone 3G’s screen on my t-shirt’s left sleeve seemed to leave a thin film of oily residue spread uniformly across the entire surface,
rendering everything a bit hazy.

Will people buy the iPhone 3GS because it’s got an oil-repellant screen coating? Certainly not. But in adding the coating, Apple combats a weakness—albeit
minor—in the design of the iPhone. Given how few changes Apple made to the iPhone’s exterior, this is clearly a company that feels great confidence in its
current product designs. Instead of revamping the phone’s look and feel, the company’s designers are instead focused on the little things, like making it easy to
wipe off greasy fingerprints.

That said, I have to point out that many iPhone users choose to protect their iPhone’s screen from hazards more noxious than oil by using some sort of screen
protector. When you see those people on the street, whatever you do, don’t say the word oleophobic. It will just remind them that this is one feature they’ll
have no use for.

The S is for “speed”
The lack of external changes belie what’s going on underneath the iPhone 3GS’s glass and plastic exterior. The iPhone’s last upgrade added a faster cellular
radio and a GPS chip, but otherwise, the iPhone 3G’s internals were largely unchanged from the original iPhone. The iPhone 3GS, on the other hand, is a
major step forward in terms of the iPhone’s technological underpinnings. Its processor runs at 600 MHz, compared to previous models’ 412MHz. It’s got
256MB of RAM, compared to 128MB in previous models.

The result is an indisputably faster device, not just at some tasks, but at every task. The iPhone 3GS booted faster than any other iPhone OS-based device,
and launched every app I tried in record time. Its Safari browser had the dramatically fastest JavaScript engine as measured by the SunSpider benchmark, and
loaded Web pages dramatically faster as well. Every aspect of using the phone felt noticeably faster on the iPhone 3GS than on the iPhone 3G. Even actions
that only took moments before now happen instantaneously.
