iPhone 4: The detailed review

iPhone 4: The detailed review
New York: Apple's new iPhone, its fourth in four years, reaches stores on Thursday. Ordinarily, this is where you'd expect to find a review of it. But honestly -- what's the point?

The iPhone 4 is already a hit. AT&T  says that it received 10 times as many preorders as it did for the iPhone 3GS last year. On the first day of taking orders, Apple processed 600,000 requests -- before its ordering system, and AT&T's, descended into chaos.

In short, the public seems to be perfectly capable of sniffing out a winner without the help of tech critics.

On the other hand, the new model won't do anything for people who detest the iPhone. It wouldn't matter if the new iPhone could levitate, cure hepatitis and clean your gutters; the Cantankerous Committee would still avoid it.

Despite the strong initial, positive reaction, this must still be a nerve-racking time to be Apple; the iPhone is no longer the only worthy contender. Phones running Google's Android software are gaining rave reviews and packing in features that iPhone owners can only envy. The Android app store is ballooning, multiple phone makers are competing, and Google updates the software several times a year. Apple releases only one new model a year, so the new iPhone had better be pretty amazing to compete.

It is.

The first thing you notice is the new shape. Despite a beefier battery (16 percent more likely to last a full day), a faster processor and upgraded everything, the new model is still noticeably thinner and narrower than before. How is that possible? In part, the trick was squaring off the back. It's no longer gracefully curved -- a design that, if you think about it, created wasted space around the rectangular components. The new iPhone is two glass slabs, front and back, wrapped by a stainless-steel band.

The result is beautiful, and since there's no more plastic, it feels solid and Lexus-like. But it no longer feels like a soothing worry stone, and it's now impossible to tell by touch which way it's facing in your pocket. The new metal mute and volume buttons are much stiffer. Still, Apple says the iPhone 4 is the world's thinnest smartphone, and most people will approve of the trade-offs.

The new phone uses the same custom chip that's in the iPad; it's really, really fast. It makes a difference every time you tap the touch screen.

It's not the first phone with both a front and back camera. It's not even the first one to make video calls. But the iPhone 4 is the first phone to make good video calls, reliably, with no sign-up or setup, with a single tap. The picture and audio are rock solid, with very little delay, and it works the first time and every time. This feature, called FaceTime, is pure Apple.

However, you can enjoy this classic "show Grandma the baby" fantasy only if you and Grandma both have the iPhone 4, and only when you're both in strong Wi-Fi hot spots. Both limitations may change in time; other software companies are free to create FaceTime-compatible programs for other gadgets. And Apple implies that next year, you'll be able to make such calls over the cellular airwaves. Clearly, Apple is giving its ball and chain, AT&T, time to get its network ready.

The new screen, with greater contrast, is excellent. It packs in four times as many pixels as before; at 326 dots an inch, it's now the sharpest phone screen on the market. Now, "the screen isn't sharp enough" wasn't exactly a common iPhone complaint before. But it's easy to see, and appreciate, the improvement in clarity of text, pictures and videos.

There's a new 5-megapixel camera, too -- better, though it's still no rival to a real camera. The actual moment of photo-snapping is an instantaneous affair now, freed of the take-your-time sluggishness of last year's model. Apple has finally deigned to give us a small, bright LED flash, too. You can make it stay on when you're filming -- a convenient video light for very close-range subjects.

Speaking of video: the new iPhone takes great-looking 720p high-definition video; now there's the equivalent of a Flip camcorder in your phone.

Furthermore, for $5, you can install iMovie for iPhone. This little app lets you trim and rearrange video clips, add music and credits, drop in photos with zooming and cross-fades, and then post the whole thing directly to YouTube.

Frankly, the whole concept sounds a little ridiculous; video editing on a phone? You might as well introduce Microsoft Excel for Hearing Aids.

But you watch. The way life goes, some iPhone production will win at Cannes next year.

Now, peculiar as it may sound, phone calls have always been the iPhone's weak spot. It took too many steps to dial. Audio quality wasn't state-of-the-art. And from Day 1, dropped calls in several big cities have driven people there wiggy.

With the iPhone 4, Apple tried to relieve the wigginess. Sound is much better on both ends of the call, thanks in part to a noise-canceling microphone and an improved audio chamber (which also helps speakerphone and music sound). The stainless-steel edge band is now part of the antenna. The new phone is also better at choosing the best channel for connecting with the cell tower, even if's not technically the strongest one. (Ever had four bars, but a miserable connection? Then you get it.)

Does any of this mean no more dropped calls in New York and San Francisco? No. But there do seem to be fewer of them.

The even better news is the new operating system, now called iOS4, which became available this week, free to owners of recent iPhone and iPod Touch models. (Apple dropped the word "iPhone" from the OS's name because it also runs the iPad and the iPod Touch.)

Three big-ticket features in this software upgrade make a huge difference. First, multitasking.

Apple has consistently maintained that running several programs at once eats up the battery. So iOS4 permits multitasking of certain important functions -- for example, Internet radio can keep playing, and GPS apps can keep updating, while you work in other programs. Other apps go into suspended animation when you switch out of them. They use no power and cost you no speed, but you don't have to wait for them to start up when you return to them.

Second, when you give the Home button a quick double-press, a new app switcher appears at the bottom of the screen. Here are icons for all your recent apps (including the ones you suspended). After three versions of iPhones, you can finally jump directly from one app to another without a layover at the Home screen.

The third big change: you can now file your apps into folders. (You drag one icon atop another to create a folder containing them both.) Each folder can hold 12 icons, meaning that download-aholics can now install 2,160 apps on a single iPhone. (Well, it's a start.)

Those over 40 can now bump up the type size for e-mail, notes, text messages and address book entries. The Mail app can group your messages into threads (back-and-forths on a single subject), and you can view all your e-mail accounts in a single Inbox. A new spelling checker lets you tap an underlined word to see correction suggestions.

The new iPhone software, in other words, is sweet and free, and you should not hesitate to get it.

The new iPhone itself is sweet but not free. The 16-gig model costs $200 (the 32-gig model costs $300), but only if you're a new customer or an existing iPhone owner whose contract expires this year. (For more on prices, plans, tethering and other gory details, see my post Wednesday at nytimes.com/pogue. Disclosure: I'm the author of an iPhone how-to book, written independently of Apple, which I'm updating.)

Now, the iPhone is no longer the undisputed king of app phones. In particular, the technically inclined may find greater flexibility and choice among its Android rivals, like the HTC Incredible and Evo. They're more complicated, and their app store not as good, but they're loaded with droolworthy features like turn-by-turn GPS instructions, speech recognition that saves you typing, removable batteries and a choice of cell networks.

If what you care about, however, is size and shape, beauty and battery life, polish and pleasure, then the iPhone 4 is calling your name.

But you probably didn't need a review to tell you that.
