iPhone 3G review

Onto the hardware. Let's start with the husk: Once, I sat down on a twisted key, putting a giant scar across the aluminum back of my iPhone. With that one exception aside, my iPhone's abused-to-hell case still looks strong and shiny.

The new case is made of smudge-able plastic, and last time I checked geek material lust hierarchy, plastic was a distant ranking of 452342 places behind aluminum. The effect is that the case, feels lighter, warmer and thicker but also cheaper than before. And in your hand, picking up a slightly warm iPhone, it feels almost more organic. Between that and the the rounded shape, which fits far better in the hand, it's like you're cupping a warm baby bird. The old phone by comparison feels like its a better quality device, with the spiritual heft of a German machine.

The new case is lighter but actually thicker; still, it feels less significant and durable. The case did survive being put in a bag full of keys and rubbed vigorously. Only some of the silver Apple logo on the back got visibly scratched. The case is also a lot easier to send radio waves through than the previous case-useful as this phone has many more radios-although reception improvement was not noticeable. [UPDATE: Actually, it is much better, in both EDGE and 3G mode] Also, if you place the new model on a table, it rocks when you tap the screen, so you can't use it as a table top computer anymore. And the case is very easy to smudge.

The black color is available in both sizes, but the white only comes in pricier 16GB, much to the chagrin of boyfriends who promised to buy their significant others one in the pale tint

The screen is slightly warmer in color temperature (more yellow than blue), slightly brighter (even when considering decay over time) and the daylight viewing is better, but it's the same 3.5-inch, 480x320 resolution screen. And it's still gorgeous.

Oh, the headphone jack isn't recessed anymore, so you can use whatever headphones or adapters you want. And the lock and volume buttons are recessed slightly more and are metal. The speakers and earpiece have a metal grill behind them. All this, to great effect.

To mention the 3G is to bring up painful memories, the time I've lost waiting for web pages to load on the iPhone, or standing on street corners waiting for maps to

Our tests in AT&T's aggressively built-out NYC area showed the 3G connection is 4.8 times faster than the old EDGE connection. When you turn off 3G and do an EDGE-to-EDGE test between older and newer models, they both perform the same. The GPRS (850, 900, 1800, 1900) and UMTS/HSDPA (850, 1900 and 2100 MHz) cellular radios have the advantage of some design improvements, including the use of the steel ring around the screen as an antenna and the electronic transparency of the now all plastic back.

Wi-Fi reception is better. In a side-by-side test with the old iPhone, we walked away from an access point, the old iPhone's connection died at 100 feet and the newer one lasted to about 120 feet. And there's a new Airplane mode that turns off cellular but powers up Wi-Fi for airline internet.

At the end of a day with lots of email and browser use, or media playback, my old iPhone would be begging for a serious dock charge. How does the iPhone's 3G connection affect that?

The downside of such speedy downloads is a reduced battery life, something the original couldn't stand to lose much of. We're do more testing of that soon. But here's an interesting thing: According to the data out there, the iPhone 3G has better battery life using 3G than the old iPhone does using EDGE. Let me explain. Apple's official browsing battery life rating on Wi-Fi is 6 hours for both models. They never rated the EDGE battery life but most testers found it to be about 25% less than Wi-Fi. That's 4.5 hours. The iPhone 3G rating is 5 hours of browsing. Apple is claiming that it's 5 hours for both the new iPhone 3G and the EDGE on the old one. We shall investigate such claims soon. But I wish Apple would take me up on my idea for using the 3G only for active browsing, maps and certain apps that need it, dynamically switching to EDGE for IMing, email downloading and weather checking.

UPDATE: Battery life has been noted to drain very quickly, but because I find myself using the phone a lot more often thanks to the added usefulness of apps. 3D gaming is also a killer on battery, far worse than anyone has claimed so far, thanks to the constant use of CPU, GPU and LCD backlight. Here is a roundup of nine battery tests taken from the best reviews, averaging about 5 hours for 3G talk (good) and 3-5 hours for "mixed use". Regardless of life, here are some tips on increasing iPhone 3G endurance and some gadgets that can help extend battery life

This is really not a revolutionary phone. It's more like the iPhone we wished Apple made last year. But basics, like cut, copy and paste are still missing. (As is MMS, thanks for the reminder, commenters.) As well are the ability to use the phone like a hard drive. Other than that, we're hoping for some more revolutionary changes to come by software update. And let's take a moment to remember how many developers are making killer iPhone programs right this second. There's the revolution.

So the hardware is interesting in the iPhone 3G, but the real story here is the new iPhone OS 2.0 firmware, which we've written about in depth here. You manage to install that, old iPhone users, you've got about 80% of this new iPhone's mojo. But if you're not making your calls on an iPhone yet, well, what are you waiting!
