Compass / Google Maps

It may seem like an odd choice, but Apple decided to stick a proper compass inside the 3G S. At first we were a little perplexed by the addition, since we've gotten in this weird habit of expecting bolder moves from the company. Still, in practice the inclusion of a hardware compass is actually really helpful when it comes to doing things like navigating a new city. As far as the hardware is concerned, the compass seems to do what's promised with pretty impressive accuracy.

The Compass app itself, viewed as a standalone product, doesn't really do much for us. We rarely have a need to know which direction we're facing or where north is in relation to where we're standing -- it's just not a piece of data we typically use. The combination of Google Maps and the compass, however, is a powerful marriage that could put an end to many of your navigation woes. Within Maps, you now have the option to not only locate your position via GPS, but orient the map to the direction you're facing. Once the compass picks up your bearing, it rotates the map to reflect. This may not sound like much, but if you've ever tried to walk a new city using just maps and geolocation, you'll understand quickly. Being able to not only see your surrounding landmarks, but how they relate to you from a directional standpoint is incredibly useful, and we found ourselves reaching for the help often with the 3GS. One sour note was that you're not treated to the same reality-bending feat of using the compass while in street view (as Android does -- always great at parties), though it's a minor complaint. We can't say what extended functionality the compass will hold, but the pairing with GMaps here is enough to make it a worthy addition in our opinion.

Voice Control

Voice Control is a bit like an answer to a question that no one asked. The basic premise is that Apple has given 3GS owners the ability to control their phone via simple voice commands, relayed through a glitzy Voice Control homescreen (which is accessed by holding down the home button for a few seconds). As you issue commands, the screen provides fly-bys of possible actions, ostensibly to make the process a bit easier on those with a blown short term memory. In practice, the application performed admirably when we made specific requests, whether it was dialing contacts, or playing a particular band -- though it wasn't without its hang-ups. The first problem we encountered is that it would sometimes just mishear us altogether, for instance, we asked it to "play M83" and it thought we wanted to listen to a playlist called "Pre" (oh the irony). Another irksome behavior is that you can ask Voice Control things like what song is currently playing, but after telling you, the app closes itself, forcing you to reopen if you want to change the track or perform another action. This seems like weird UI design to us -- why wouldn't Voice Control stay open until we were ready to close it? We also discovered that the range of options for voice activated functions are quite limited -- if you want to do anything beyond controlling music playback or making calls, you're pretty much out of luck.

There's clearly a lot of use for something like this when driving or working on something which keeps your hands away from your phone, though you still have to engage the app physically, so we're not sure how much you'd get out of it in those situations. The whole concept seems something very much in the vein of Cover Flow -- a really impressive component for the phone that just doesn't have a ton of practical use. Yes, your friends will think it's pretty cool, but as a pragmatic group of gadget nerds, we don't see a tremendous need for this functionality. Perhaps Apple will give it a little more undercarriage work in future versions of the OS, because we see lots of interesting places they could take it.

Software

As we said in the opener, the 3GS launch isn't just about the hardware -- in fact, you could argue that it'shardly about the hardware. The biggest changes with this device really come in the form of software tweaks, and to a point, the software tweaks provided by iPhone OS 3.0. Apple really piled on the fixes and additions in its latest OS iteration (the company boasts of 1,000 new APIs for developers), and there's plenty to plow through that up until now has only been the domain of those lucky / hard working few. What's all the fuss about? See below.

We'd like to preface this section by saying that because we're testing a US device, MMS and tethering options are disabled thanks to AT&T's current policies on the services. Obviously, not being able to properly test two of the most anticipated aspects of the new OS is disheartening, and while we could hack a solution to get both working (see here), it's not a reasonable option for most end users right now, and probably wouldn't be fair to include in this review.

On a "brighter" note, AT&T claims it will be delivering MMS to the iPhone come late Summer as part of its standard SMS packages (no word on tethering), though we think it's patently absurd that the second largest carrier in America -- a carrier which currently has MMS enabled for all of its other devices -- is failing to make this available at launch. Judging from the reaction to this news during the WWDC keynote, it would seem that most others agree. Apple included.

Cut, copy, and paste

Of all the features added to the new 3.0 cocktail, copy / paste is easily the most talked about. Perhaps because it was such an obvious feature to leave out to begin with, or perhaps because Apple made it through multiple updates with no change (till now). Regardless, the iPhone line now has the ability to perform one of the most basic tasks known to computing. So how does it fare? Well, it's actually a pretty smart implementation of the process on a mobile device -- one of the best we've seen. To grab a chunk of text, you simply tap on the section you want to grab and the phone tries to figure out just how much you meant to select. Usually it's pretty smart about what you want (sort of the copy / paste version of Apple's predictive text input), but it also gives you anchors to grab on the top, bottom, left, and right of the selection box, allowing you to pull your copy area out as needed. A contextual menu appears above or below your selection, and changes based on what stage of the process you're in. To paste you just tap on an empty spot in a document, and the menu presents itself again. For undoing actions, you shake the phone (cute, but a little annoying -- we would have preferred a menu item).

The beauty here is that unlike competitors such as the Pre or Android, iPhone copy and paste doesn't just let you grab text -- you can grab whole chunks of mixed media, like text and images, and it will copy the content with proper formatting and elements. If you want to pull out a section of a webpage, for instance, the function elegantly allows you to zero in on the area you want to copy and easily transfer it into an email or document without losing any components (unless you're pasting into a text only area, like Notes, which strips out formatting and images).

While we don't think the wait was necessarily justified for a feature so simple (and so necessary), we do think Apple has pulled off a tremendously useful implementation of the process. It's the kind of thing you'll miss once you go to another device without such broad and universal functionality.

We mentioned that Apple didn't really make any cosmetic changes to the phone, but that's not entirely accurate. While the 480 x 320 display on the iPhone 3GS is technically identical to its predecessor's screen, it adds one small feature which should make some users extremely happy.

The company has changed the treatment on the surface of the touchscreen, utilizing an oleophobic coating -- essentially a protectant that's highly resistant to fingerprint smudging. For those of you constantly wiping burger grease, WD40, and various other toxic materials from your iPhone, this will come as a tremendous little perk. The most surprising thing about the tech is that it actually does what the company says it will: namely, it resists new smudges and wipes almost entirely clean with a single swipe on a pant leg. This wasn't exactly the most pressing issue we had with the phone, but it's nice to know that Apple is innovating in the dirty screen space.

Camera

A camera tweak is a big deal for iPhone fans -- after all, they've had to suffer through not one, but two iterations of a phone with a paltry 2 megapixel camera, no autofocus, and no flash. Apple has tweaked two out of three here, and as Meat Loaf tells us, that ain't bad. The 3GS upgrades the built-in camera to a 3 megapixel version -- not insanely great, but at least competitive -- and has added an autofocus function with a nifty software tie-in. Instead of having to use a gross physical button to snap your shots, the iPhone continues to rely on its onscreen trigger, but cranks up the use of that big display by allowing you to focus in on subjects based on where you tap. In our experience, the parlor trick actually turned out to be quite useful, accurately zeroing in on what we wanted most of the time. Struggles to focus were minor at best, though you won't be able to do any heavy macro work here, and during video recording you're stuck with a constantly focusing lens -- no tapping allowed.

As we said in the intro, there is nothing visually different about the iPhone 3GS versus the iPhone 3G, save for the lettering on the back, which is now mirrored like the Apple logo. While we had seen leaked images of a matte finish, bezel-free version of the device, when push came to shove, what we got was essentially a carbon copy of the iPhone 3G. In terms of the general elements of the phone -- the plastic casing, mute switch, home and power buttons, etc. -- there is no change at all. In fact, if you were to lay this phone and its predecessor next to one another face up, the new model would be indistinguishable. Of course, the 3GS is not just a clone of the previous device, and Apple has made most of its significant changes inside the phone.

Internals

First off, the company has supercharged the CPU of the 3GS (remember, the S is for speed), jacking up the processor numbers from 412MHz to a rumored 600MHz. Additionally, the RAM is said to have doubled from 128MB to 256MB, the phone is offered with 16GB or 32GB of storage, and Apple has swapped out the previous graphics chip for a new version -- dubbed the PowerVR SGX -- which adds support for more robust visuals via OpenGL ES 2.0. All this should mean that end users will see a noticeable difference in app speeds and loading times (Apple claims an average of 2x faster loads, though since the company has been cagey about upgrade details, it's hard to know what the real differences are).

So, do the revamped insides equal an improved experience on the phone? Kinda.

For our oft-used phone actions -- flicking through homescreens, calling up search terms in Spotlight, scrolling through long lists -- we definitely felt like the 3GS was snappier than its predecessor. It wasn't like the doors were flying off, but there was a noticeable bump in speed, particularly when it came to initial data loads (how quickly you see content pop up within an application). When it came to opening apps which pull lots of that kind of content, like Contacts, Calendar, or Messaging, we saw an even more noticeable improvement. Comparing the 3G and 3GS side-by-side yielded small but absolutely palpable differences -- the 3GS does seem to eliminate quite a few of the hangs we find maddening as we go through our day. It's not the perfect salve, but it's a start.

We're excited by the cranked up CPU, but in our experience you'll see lowered load times (though obviously not as drastic) if you take a standard 3G and do a full restore, so there is the lingering question of whether or not the jacked-up feel of the 3GS will last, or will begin to bog down after months of use and heaps of data.

If it ain't broke, don't fix it -- right? We know countless reviews of the iPhone 3GS may begin with that cliché, but there's little chance you'd find a better way to describe the strategy that Apple has just put into play with its latest smartphone. In many ways, the 3GS is a mirror image of the iPhone 3G; externally there's no difference. It's inside where all the changes have happened, with Apple issuing a beefed-up CPU, new internal compass, larger capacities for storage, and improved optics for its camera. More to the point, the release of the 3GS coincides with the launch of iPhone OS 3.0, a major jump from previous versions of the system software featuring highly sought after features like cut, copy, and paste, stereo Bluetooth, MMS, tethering, video recording, landscape keyboard options for more applications, and an iPhone version of Spotlight. At a glance, what Apple seems to be doing is less a reinvention of the wheel and more like retreading the wheel it's already got (and what a wheel, right?). So, do the iPhone 3GS and OS 3.0 tweak the details in just the right places, or has Apple gone and gotten lazy on us? Read on to find out.
