iPhone 3GS review

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.
Hardware


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.
A spot where we really saw the fruits of Apple's labors (and one we don't expect to decline as you pile on data) was actually in the more graphically intense apps for the phone. Comparing a CPU-hungry 3D game like Resident Evil: Degeneration on the 3GS with the same title 3G yielded striking results. The load time was drastically reduced, and rendering and frame rates on the game were noticeably smoother than on the older device (though game speeds stay the same) -- a side effect of the more powerful guts we'd hoped to see, but weren't sure would be so stark. If you're an avid gamer looking for the device with more power, the difference will be crystal clear: the 3GS obviously flexes in this department.

Display


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.

We do have some complaints about exposure, which seems to be permanently cranked to "blinding," and while the shutter speed is faster than on the 3G, it's still not quite snappy enough for our taste. Hey -- we guess we should just be glad they gave us an extra megapixel, right?

Software


As we said in the opener, the 3GS launch isn't just about the hardware -- in fact, you could argue that it's hardly 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.

Push notifications



Way back in June of 2008, Apple promised that we'd see push notifications -- instantaneous alerts for emails, messages, and other app-related notices -- due in an OS update come that September. Needless to say, the fall came and went without so much as a mention of the software addition. Earlier this year, Apple showed off the functionality again at the iPhone OS 3.0 preview, combatting arguments for true multitasking within the iPhone operating system by saying push would not only work as a surrogate for most background tasks, but would allow the devices to retain sufficient battery life. Background tasks, Apple warned us, create a drain on power that would have users running for their chargers far too often.

So -- do push notifications take the place of background tasks? Do they give the end-user the feeling of constant connectedness the way Apple seems to intend them to? In our experience, not quite. At the time of this writing, there are only a few apps actually employing the service, though we're sure more will come. Overall, where push is really useful is in receiving updates or messages -- individual pings which direct your attention towards a particular application -- but they don't keep you in the stream of information the way an AIM session running in the background does. Yes, you get alerted to new messages (or in the case of something like Tap Tap Revenge, challenges), but those appear as either one of the iPhone's annoying pop-ups, or as a background audio notification coupled with a growing message counter for a particular app (AIM for instance). The service is extremely useful, and we're happy that Apple is endeavoring to make it available for all of its developers, but from a practical perspective, it doesn't feel that different than an email notification or a calendar event. In short, it will help you stay connected, but it won't take the place of true multitasking, and unless Apple finds a less obtrusive notification solution, it could actually create quite a mess. Besides those obvious issues, we're still not seeing push for the things we really want, namely, Gmail. We don't know when (or if) a rollout of said feature is planned, but we're guessing it can't be too far off for a device which now has central functionality orbiting around this feature.

Ultimately, we still feel strongly that true multitasking can't be replaced by these notifications, and if there's anything we learned from using the Pre, it's that background tasks can be handled elegantly without a mind-blowing hit to battery life. For a company which prides itself on advanced battery tech, you'd think instead of shying away from the challenge, Apple would be looking for ways to innovate in this space.

Spotlight


We've got to hand it to Apple -- the company has really answered the call when it comes to search functionality on the iPhone. The addition of Spotlight to the iPhone OS is quite notable for two reasons: first, it gives you homescreen access to a full search of all your content on the device, including notes, email, contacts, calendar events, and applications. Secondly, it provides new search functionality within mail that not only lets your get at downloaded messages, but extends the hooks into server-side content. That's a bit of a stunner, as we can't count the number of times we've needed to fish some info from an email that had long moved outside of our 200 message limit (and what's up with that anyway Apple?). Spotlight searching works flawlessly in email, but we have a few gripes about the phone-facing implementation.

To start with, in order to navigate to your Spotlight screen, you have to either assign the home button double-tap shortcut to take you to the search window, swipe back when you're in homescreen view, or single tap once to get to your first page, then again to get into Spotlight. It all seems a bit complicated to us -- what would have made more sense was some kind of universal gesture... like maybe that long home button press reserved for Voice Control (more on that in a bit). Another problem is that you still have to jump through multiple hoops to get to the content you're looking for, particularly with contacts. Once you bring up a name, you have to actually jump into the contact card to call or send a text message -- why isn't this info accessible from the search window? As with a lot of processes on the phone, you still feel like you're clicking through way, way too many screens to get where you need to be.

Video recording / editing


Okay -- you got us. Video recording on the iPhone 3G S is really quite impressive, and there are two reasons why. For starters, the phone handles pretty fantastic looking VGA video at 30 FPS, which makes for not just passable mobile video, but usable mobile video. The size, clarity, and smoothness of the sequences we shot looked tremendous to our eyes -- certainly on par if not outclassing many of the contenders in this space. In our opinion, the 3GS video quality is high enough that we'd consider this a viable stand-in for lower end camcorders or flip cams -- if you want to capture your kids at the park but don't want to come packing a ton of gear, this produces totally reasonable results.
The second reason we're a fan of the 3GS video functionality is simple: editing. After you snap some video, you can easily pull out just the section you want to use in a kind of dumbed down iMovie edit window, which gives you a timeline of your clip, replete with a preview of the action. You can long-press on the section you're editing to see a more detailed view, and you can pull either the start or end points to snag just the section you want. We love the fact that you can grab and cut video in-phone without having to offload anywhere else, but we'd love it even more if OS 3.0 allowed for non-destructive editing of the clips. As it is now, once you cut something down, you're done -- there's no way to retrieve the full length version of the video. We're hoping in future version Apple gives users either the option to retain the deleted sections, or at least the option to copy the clip over to a new file. We wouldn't scoff at an option to splice or merge multiple clips together either, but we don't want to break the bank with our lofty requests.

One other nice feature that's been tacked on the video tool is the ability to auto-compress and upload to YouTube, MobileMe (a 45 second video took about three minutes to up over WiFi), or send a .MOV in an email. If we had a device that could actually utilize MMS, there's an option for that as well.

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.

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.

iPhone 3GS

Speculation is at fever-pitch in the run-up to the Apple 2009 WWDC: what will the new iPhone Video / 3G / 3.0 / 3GS look like? And will we get a boom-one-more-thing from Steve Jobs? In IT Blogwatch, Richi Jennings watches the fanbois drool in this pre-view of today's Worldwide Developers Conference.

Apple's WWDC 2009 is almost upon us and, by the hype, you'd think the one and only thing we'll see at the event is a new iPhone. ... [Rumored:] a magnetometer (compass), better camera (3.2 megapixel with auto-focus) and some minor aesthetic changes (black matte back and black rim). ... A forward facing camera for video chatting. ... Will range in size from 4 to 32GB and start out at $99-149 with plan. It may even be called the "iPhone Video" or "iPhone 3GS" and have FM broadcast/receive capabilities.
