iPhone 4 review

The iPhone 4 is no small thing to review. As most readers of iGadgets are well aware, in the gadget world a new piece of Apple hardware is a major event, preceded by rumors, speculation, an over-the-top announcement, and finally days, weeks, or months of anticipation from an ever-widening fan base. The iPhone 4 is certainly no exception -- in fact, it may be Apple's most successful launch yet, despite some bumps on the road. We've already seen Apple and AT&T's servers overloaded on the first day of pre-orders, the ship date for the next set of phones pushed back due to high demand, and die-hard fans in line outside of Apple locations a week before the phone is actually available. It's a lot to live up to, and the iPhone 4 is doing its best -- with features like a super-fast A4 CPU, a new front-facing camera and five megapixel shooter on the back, a completely new industrial design, and that outrageous Retina Display, no one would argue that Apple has been asleep at the wheel. So the question turns to whether or not the iPhone 4 can live up to the intense hype. Can it deliver on the promises Steve Jobs made at WWDC, and can it cement Apple's position in the marketplace in the face of mounting competition from the likes of Google and Microsoft? We have the answers to those questions -- and many more -- in our full review, so read on to find out!

Hardware

 Perhaps the most notable change with the new iPhone is the drastic industrial design overhaul -- Apple seems to have completely rethought its strategy on how the phone should look and feel, and the results are nothing if not striking.

Industrial design

 In his WWDC keynote, Steve Jobs likened the design of the iPhone 4 to that of a "beautiful, old Leica camera," and as we've said before, he wasn't off the mark. Instead of hewing to the curved, plasticky, silver-bezeled look of the iPhone 3G and 3GS, the company has turned the casing and face of the device into something decidedly more detailed and sophisticated. From the design aesthetic through to the actual build process, Jony Ive and his team have reset what we expect in an iPhone, coming up with something that clearly harkens back to the retro-future Braun designs of Dieter Rams. The iPhone 4 is made up of three basic parts: two pieces of smooth, strengthened glass, and a stainless steel band which wraps around the sides, top, and bottom of the phone. The effect is clean but not simple, and Apple has added little details, like altered volume buttons (what used to be a rocker is now separated into circular clickers labeled + and -), and notches in that metal band which serve to improve radio connections (more on that in a minute). The phone is noticeably thinner than the 3GS at .37 inches compared to .48 inches, but it weighs the same 4.8 ounces, making the whole package seem tighter and denser. It feels great in your hand, with good heft, although it might take a little time to get used to the lack of a rounded back if you're coming from the 3G or 3GS.

 We can't overstate how high-end the design of the iPhone 4 is. The 3GS now feels cheap and chubby by comparison, and even a phone like the HTC Droid Incredible -- which just came out -- seems last-generation.

As we said, there are three main pieces of the phone, which together create an effect not wildly dissimilar to that of an ice cream sandwich. You know, but far pricier... and not edible. The face of the device is made up of extremely strong glass which Jony Ive says is "comparable in strength to sapphire crystal, but about 30 times harder than plastic." A small slit for the earpiece and the front-facing camera are embedded in the glass above the display, with the familiar home button towards the bottom -- a button we should note feels much clickier than on our 3GS. On the left side of the phone you've got the new volume buttons, a redesigned mute switch, and a small notch towards the base of the unit. On the right side is the Micro SIM slot and another notch in the band at the bottom, and up top there's the power / sleep button, headphone jack, another notch, and new noise-canceling microphone. Along the bottom is a speaker, microphone, and the 30-pin dock connector port. The backside of the phone is made from the same kind of ultra-strong glass as the front, interrupted only by the new five megapixel camera, its LED flash companion and, of course, the Apple logo.

 

Overall, the iPhone 4 outclasses pretty much every smartphone on the market in terms of industrial design. It just comes off like a far more expensive device, like a Mobiado or Vertu -- but better designed. And it's not just the way the phone looks; the materials feel good -- premium -- in your hands. The first few days we had our test unit, we were definitely freaked out about dropping or losing the phone, and some of that had to do with the fact that it's just a really beautiful device to use and hold.

Internals

It's not just the face of the phone that's undergone a transformation -- the iPhone 4 is all new inside as well. For starters, Apple has moved on from the Samsung-built ARM Cortex-A8-based CPU used in the 3GS to its custom A4 chip used in the iPad, which funnily enough... is an ARM Cortex-A8-based CPU. While the company hasn't yet said what the clock speed of the processor is, we're guessing it's something below the 1GHz touted for its tablet cousin. The phone is definitely snappier than the 3GS, so we're not about to volley complaints just yet -- in particular, graphics seemed to render faster, and overall responsiveness was slightly higher, though admittedly, it wasn't blowing the doors off the joint. It's certainly faster, but the 3GS wasn't hurting on speed to our eyes, so it's not as wildly noticeable a leap as the 3G to the 3GS.


As usual, Apple isn't fessing up about the RAM situation, though we have on very good authority that the iPhone 4 has 512MB onboard, a big step up from the 256MB in the previous model and the iPad. We would have liked to see it futureproofed with something like 1GB, but then again, Apple's got to sell a new phone in a year. As far as internal storage goes, you can buy the new iPhone in either 16GB ($199 on contract) or 32GB ($299 on contract) capacity -- fine for now, but since the company has just introduced 30FPS 720p video recording, you could find yourself outgrowing that number pretty quickly. It's a little odd, in fact, that the company didn't double down here and bump the capacity to 64GB, as it's recently done with the iPod touch. In terms of wireless, the iPhone 4 is packed with an 802.11n WiFi radio, as well as a quad-band HSUPA chip and Bluetooth 2.1.

 The redesigned housing allows for a much larger lithium-ion battery on the inside, providing improved numbers for Apple's life ratings (more on that in a moment), though it's still not easily replaceable. Additionally, the new phone has those two new cameras (VGA up front, five megapixels with LED flash around back), a new second microphone used to combat background noise while on calls (similar to the Nexus One), a gyroscope in addition to the standard accelerometer, a light sensor, and a proximity sensor. As with the 3GS, an AGPS chip and compass are bundled somewhere in that tiny frame as well.
Of course, the big internal story is what has become external: namely, the UMTS, GPS, WiFi, and Bluetooth antennas. Apple has made the stainless band around the phone essentially a couple of big antennae, and they seem to be doing a pretty good job at hanging onto radio signals. The big question is obviously whether or not this fixes or helps with the constant dropped calls iPhone users on AT&T's network have gotten used to. Well in our testing, we had far, far fewer dropped calls than we experienced on our 3GS. Let's just say that again: yes, the iPhone 4 does seem to alleviate the dropped call issue. It wasn't perfect, and we had some connection issues in downtown New York City in particular, though it's tough to say if it was the fault of our phone, the cluster of buildings we were near, or the person we were speaking to, who was on a 3GS in the same location.
 

Display

 By now you should know that iPhone 4 has an all-new display, as well. Apple is calling the LED backlit, 960 x 640 IPS screen the "Retina Display" due to its high resolution and pixel density. At the same 3.5-inches as the older screens, the new display manages an insane 326ppi pixel density along with an 800:1 contrast ratio. Steve made a huge point about the science behind this technology during his keynote, claiming that the resolution of the screen essentially tops what is perceivable by the human eye. There have been some debates as to whether or not this argument holds water, but we can tell you this: to our eyes, there has never been a more detailed, clear, or viewable screen on any mobile device.

Apple iPhone 4 pre-orders now sold out?

We have no idea how this happened given the insane problems Apple and AT&T have had processing iPhone 4 pre-orders today, but lots of people (including us) are seeing a July 2 ship date at Apple's online store, or about a week after the next-gen iPhone launches on June 24. Frankly, that's amazing -- we can only imagine the kind of sustained rush it took to cause a sellout of a product virtually no one was actually able to order. So that's Apple and AT&T both sold out -- at this point it's looking like standing in line somewhere come launch day is going to be your best bet, but we'll let you know if we hear any better news.

600,000 iPhone 4s pre-ordered, Apple apologizes for issues

We were amazed last night to see both Apple and AT&T sell out of iPhone 4 pre-order units despite the sustained ordering issues, and now we know why: Apple managed to move 600,000 iPhones in just a single day. Yes, that's a lot -- Apple says it's the largest number of pre-orders it's ever taken in one day, and AT&T says it's ten times as many orders as it took for the iPhone 3GS. It's not all sunshine and roses, though; Apple's also apologizing to the large numbers of people who simply couldn't get through yesterday, and AT&T's suspended pre-orders entirely until the device is in stock. We're guessing AT&T might also be putting the stopper on things while it gets those pesky security issues under control, but there's a chance the carrier is just trying to deal with the insane order volume coming from Apple's servers -- it served up 13 million eligibility checks yesterday, shattering the previous record by three times. All in all, it looks like Apple has a hot item on its hands here -- almost too hot to handle. Here's Apple's full statement:

Yesterday Apple and its carrier partners took pre-orders for more than 600,000 of Apple's new iPhone 4. It was the largest number of pre-orders Apple has ever taken in a single day and was far higher than we anticipated, resulting in many order and approval system malfunctions. Many customers were turned away or abandoned the process in frustration. We apologize to everyone who encountered difficulties, and hope that they will try again or visit an Apple or carrier store once the iPhone 4 is in stock.

Update: Looks like that "ships by" date just slipped once more from July 2nd to July 14th. Yikes.

iPhone 4 pre-orderers overwhelm servers, world on the brink of ending

Look up at the sky -- is it falling? It sure seems as if that kind of doom is imminent, at least if this whole iPhone 4 pre-order situation is any indication of future tragedy. We've received hundreds of tips this morning from friends near and far that iPhone 4 pre-orders aren't going through, though a few of us here on staff were able to get a confirmation during the wee hours of the morning. From AT&T in the US to O2 over in the UK, it seems that just about everyone ambling to get their name on a future iPhone 4 is experiencing a great deal of frustration. AT&T's servers seem to be completely hosed here in America, and since Apple's own online order process has to ping those to check on your contract status, neither option is... um, working. Those who decided to line up at a local store are facing similar issues; employees aren't even able to fully process pre-orders in store due to systems being overwhelmed, and no one seems to exactly know when things will be back to normal. And you thought the most enraging part of this was the inability to select a white model. Let us know how your experience has been in the poll and comments below, won't you?

Update: So, it sounds like Best Buy is taking pre-orders (even for white units), but chances are remarkably high that you're not actually getting in any line. Still, it's a working option for the moment. In other news, the Apple Store app is seeming to allow iPhone 4 orders, but it looks as if they're reserving off-contract phones (read: full price ones), so we'd only recommend this avenue if you enjoy things like "arguing about contract dates" and "yelling at brick walls." We're guessing you'll be doing both on the 24th.

BlackBerry Curve- Review Of BlackBerry Curve

When it comes to BlackBerrys, you have the really tiny one, the one with GPS, and now you can add to that list the one that just rocks. And we're not just talking about the Curve's music player or fully integrated stereo Bluetooth. RIM's latest fun-loving smart phone (available for AT&T later this spring) boasts a sharp two-megapixel camera and a much-improved multimedia software package for taking your favorite songs, pictures, and videos to go--all without sacrificing the long battery life that's made BlackBerry the device of choice for e-mail addicts.

 

Just Right Design

 

It sports the kind of sleek design that will make BlackBerry Pearl owners say "D'oh!" The Curve is just as slim as the Pearl (0.6 inches), and at 3.9 ounces it's only 0.7 ounces heavier. It slips easily into a pocket, no geeky hip holster required. Granted, at first glance this device doesn't seem as deserving of an iconic name as the Pearl, but the Curve's liquid-silver finish with chrome accents and rounded edges make it an attractive alternative to the Samsung BlackJack.

 

More important, RIM managed to squeeze in a full-sized backlit keyboard, one that makes the Curve noticeably wider than but also much more reliable than the Pearl, whose not-so-SureType keyboard doesn't always accurately guess the word you're trying to peck. In just a few minutes we were typing e-mails and entering Web addresses at a brisk pace, thanks to the Curve's well-spaced layout. Just like the Pearl and the 8800, the Curve has a trackball for simple (if sometimes erratic) menu navigation.

 

The 2.5-inch, 320 x 240-pixel display did a superb job rendering everything from Web pages and maps to photos and videos. The rest of the design is pretty straightforward. A standard 3.5mm stereo jack, a USB port, and a push-to-talk key line the left side of the Curve, and the volume buttons and camera-launch key are on the right side. The top of the device houses the Mute button. We wish the microSD Card slot weren't located beneath the battery, but chances are you won't be removing your card very often; the Curve's mass-storage mode enables easy drag-and-drop file transfers.

 

Sharp Camera, Smarter Media Software

 

What separates this BlackBerry from the Pearl and the 8800 is its robust multimedia capabilities. The Curve's 2-MP camera takes pictures good enough for 4 x 6-inch prints. Everything from a photo of a fountain in Bryant Park to a portrait of two children was highly detailed and richly saturated. We like the fast shutter speed, and a built-in flash allowed the Curve to take decent close-ups in dimly lit rooms. The Curve's inability to record video is a bummer, however.

 

The robust Desktop Media Manager software is powered by Roxio's Easy Media Creator. A split-screen interface makes dragging and dropping files to the Curve (and from the Curve to your desktop) a cinch. If you want to take some videos to go, the program will attempt to convert all sorts of files to MPEG-4, including AVI, DivX, WMV, and Xvid, so long as your PC has the right codecs loaded. Media Manager can also be used to automatically monitor certain folders for new media files, create music playlists, and edit photos.

 

Desktop Media Manager did a good job transferring MPEG-4 footage captured with our Sanyo HD1 camcorder and a 68MB WMV clip downloaded from Microsoft's site. But the software had a little trouble with a five-minute MPEG-4 clip ripped from a DVD, as the audio wasn't in sync with the video when we played it back on the Curve. Then we tried a large AVI file of a "Heroes" TV episode; the Curve was able to play the audio but not the video. (Roxio claims that a successful conversion depends greatly on how a file is encoded, so be sure that a video file can play within Desktop Media Manager before you bother transferring it.) Music files transferred without a hitch, but you have to add album art manually by editing the audio tags.

 

Media playback on the Curve was generally smooth, and the device supports a wide range of audio (AAC, MP3, WMA) and video (MPEG-4, H.263, WMV) files natively. The device's speaker puts out a decent amount of volume, but we highly recommend pairing this smart phone with a Bluetooth stereo headset. We enjoyed superb audio quality via the Curve's Bluetooth 2.0 connection when we used the Motorola HT820. Another benefit of stereo Bluetooth is that you can remotely skip tracks with a simple press of the Fast-Forward button on a headset, as opposed to the two-step process of hitting the Menu key and then selecting Next Track on the Curve. The device also supports AT&T Music services, such as streaming XM radio ($9.99 per month). We had no problem downloading the app and liked the wide selection of stations in seven genres (including Pop, Rock, Decades, Country, and Hip Hop & Urban). We didn’t mind the tinny sound quality that much over the Curve’s EDGE connection, but we experienced so many momentary drop-outs that it ruined our enjoyment of the service. We say stick to your own tunes.

 

Long-Distance Sprinter

 

Despite its multimedia prowess, e-mail is this (and every) BlackBerry's killer app. We had no problems setting up our Gmail account using the setup wizard (the device supports ten personal and corporate accounts), and we appreciated the new spell-checker function, complete with a customizable dictionary. Similar to the Pearl and 8800, the Curve lets you view Word, Excel, PDF, and JPEG attachments. Overall performance was just as fast as other BlackBerrys; the only time the Curve slowed down a bit was when we streamed music over Bluetooth while trying to surf the Web.

 

Speaking of which, the Curve's Web-browsing performance was pretty snappy over its EDGE connection. (Yes, without HSDPA or Wi-Fi.) We could start reading most sites within 7 to 10 seconds, and images filled in 10 to 20 seconds later. Call quality was generally good on AT&T's network, but as with the 8800, we wish we could get more volume out of the Curve's earpiece. More disconcerting were the two occasions when we couldn't get through to the number dialed on the first try. On the plus side, the Curve delivered excellent endurance on our tests, with the battery lasting four days with periodic use. You get only four straight hours of talk time versus five for the 8800, but that's still half an hour more than the Pearl.

 

The Curve's biggest competition isn't other BlackBerrys but the Samsung BlackJack, which currently costs only $149 with a mail-in rebate. The BlackJack's 3G data connection is only a moderate advantage because of Windows Mobile's slower browser, but its built-in camcorder and support for Cingular Video are definite pluses. On the other hand, the Curve offers a better e-mail experience, a sharper camera, and much longer battery life. Despite a few drawbacks, this is the best BlackBerry--and one of the most well-rounded smart phones--money can buy.
