I have to preface this review with an apology. It’s taken me a long time to get this review up on the site and I’m sorry for that. You knew not to expect a day-one review from us because that’s just not how we roll; we like to get a serious feel for the items we’re testing before passing judgment. I was waiting for apps to be updated with iOS 4 features, and for Apple to tell their side of the antenna story before writing the review (not to mention getting distracted with the Droid X). With that said, I hope you’ll still join me for our iPhone 4 review.

Hardware

The iPhone 4 introduces an all new design. Here’s a quick spec rundown, and as always, you can get detailed information from our iPhone 4 Portal page.

• CPU: Apple’s A4 chip (1GHz)
• RAM: 512MB
• GPU: PowerVR SGX 535
• Screen: 3.5 inch IPS display @ 960×640 (326 ppi)
• Rear camera: 5 MP with single-LED flash (HD video record capable)
• Front camera: 0.3 MP (video up to 640×480)

Design

You’d have to really despise Apple to say that they have no design talent. The iPhone 4 once again makes its predecessor feel like a toy, despite the fact that it once felt like a quality built device. The iPhone 4 is 24% thinner than the iPhone 3GS, making it the thinnest smartphone in the world (according to Apple), though despite it’s decreased thinness, it doesn’t feel thinner than the iPhone 3GS because of its square back. The iPhone 3G and 3GS had rounded backs which made them feel thinner than they really were. The result of this lack of rounded back makes the iPhone 4 feel just as thick as the iPhone 3GS.

The front and back of the device is made from glass which Apple lauds as being much stronger than plastic. I’ve somehow managed to already get more scratches on the front of the my iPhone 4 than I did over the entire course of my iPhone 3GS’s lifespan. They aren’t significant scratches, but hold the phone under the light and you’ll find quite a few. This is a striking contrast to my iPhone 3GS which never got a single scratch on it.

This could have something to do with the fact that the glass back of the iPhone 4 is somewhat slippery compared to the plastic back of the iPhone 3GS. The iPhone 4 isn’t slippery in the hand, but it frequently slides off of places where I once rested the 3GS, such as on top of my wallet, or on the arm of a couch. Some people have attributed this to the oleophobic coating which is designed to reduce fingerprint smudges (this was only present on the front of the iPhone 3GS, but it’s on the front and back of the iPhone 4).

The front and back of the iPhone 4 is glass, but there is a tiny plastic bezel that surrounds each pane. This is likely to prevent any dangerously sharp edges, as well as reducing the chance of chipping the edge of the glass.

As for the look of the device itself, it’ll definitely come down to personal preference. I, for one, think it’s a beautiful looking device, and I’m happy to see Apple working on a somewhat retro look, rather than continuing to evolve their previous design the natural conclusion of which would have eventually been the iBall — if Apple continued to simplify shapes and smooth lines.

The device feels undeniably well built, and the metal buttons are impressively solid and have no play to them. The volume buttons have been changed from a rocker bar (as they were previously on the 3GS) and separated into individual buttons. The plus and minus markings are cut directly into the metal button which gives them a sharp look that won’t be worn away over time. Both volume buttons, the silent switch, and the hold/lock button have highly satisfying clicks. Additionally, the home button on the front of the device is much more clicky than the one on the iPhone 3GS which was occasionally on the squishy end of the spectrum. If you’ve ever used an iPod Touch, then you’ll know the feeling of the iPhone 4’s home button.

Screen

Apple specifically designed the screen to have a pixel-per-inch rating that surpasses the eye’s ability to tell each pixel apart. Apple claimed that this threshold was about 300 ppi at a given distance (10 inches or so) so they made the screen 326 ppi with a 960×640 display which is 4x the resolution of previous iPhone. Just to clarify, the increase in resolution doesn’t mean more space on the screen. Instead, Apple scaled up graphics of the entire OS to 4x their original size to fit the new resolution. The result is an extraordinarily crisp screen that makes you wonder how you ever lived with the low res 480×320 screens on the old iDevices.

When I look back at an iPod Touch or previous iPhone, the screen looks quite pathetic. The iPhone 4’s 960×640 screen is the highest resolution in a smartphone, but next to an 800×480 device like the Droid X [portal page], the difference won’t be perceptible for most people. So while the iPhone 4’s display blows the previous iPhone out of the water, it isn’t wildly superior to other devices out there.

The IPS screen is reasonably readable in bright sunlight and has an impressive full 179 degree viewing angle with virtually no loss of color or contrast at even the most extreme angle.

Looks like we were one of the lucky people that got our iPhone 4 [Portal page] a day early, and fortunately that means you get to take a look at it a day early with us. Check out the video unboxing below as well as some photos. Just to note, I mentioned that the iPhone 4 doesn’t come with a SIM ejector, but I didn’t say that it also doesn’t come with a polishing cloth as the iPhone 3G once did. Stay tuned for more.

Engadget has managed to get their hands on a pre-production Dell Mini 5 [Portal page] (aka Dell streak or M101), and they’ve got a nice gallery of the device up on their site as well as a brief video. Hopefully they’ll drop some hands-on impressions later, but for now it’s pretty much just visual media. I’m most interested to see what they think of the off-centered QWERTY keyboard which is offset due to a seemingly always present numeric OSK — the keyboard could make or break this device. Check out a few shots below and jump over to Engadget for the full gallery and video.

One of the coolest features on the Nokia N900 is the pretty awesome camera. The N900 has an auto-focus 5.0MP camera with a dual-LED flash (with a sliding cover). The optics are by Carl Zeiss which are regarded as being high quality in the world of cameras. I’ve got several shots taken by the iPhone 3GS’s 3.0MP auto-focus camera and put them up against images taken with the N900. You’ll see the iPhone’s photos on the left and the N900 shots on the right. Be sure to click on the images to get the full-sized photos.

After looking through these images, it is pretty clear to see that the N900’s 5.0MP camera takes sharper images than the iPhone’s 3.0MP camera, which makes sense of course. Looking very closely though, it would appear as though the N900 also has a better dynamic range than the iPhone. What this means is that the N900 can capture a wider range of dark and light in the same scene than the iPhone can. You may have also heard of this term referred to as contrast ratio. This is apparent in most of these images if you look closely, but it’s particularly visible in the photo of the underside of the tree. Much more detail can be seen in the dark regions of the N900’s shot than can be seen in the iPhone’s. Colors appear to be more accurately represented as well. In the second to last shot of the flowers, the iPhone image seems to have oversaturated colors, whereas the N900 more accurately shows the range of pinks.

The macro mode on the N900 is probably the thing that most impresses me. The N900 has the benefit of having a dedicated hardware camera button which, when pressed down half-way, focuses the camera (with the iPhone you tap on the screen to focus). Turning on the macro-mode on let’s you get up-close and personal to objects and let’s you capture an impressive level of detail and texture.

A full N900 review is in the works, stay tuned!

I’ve just uploaded a bunch of images of the Eking S515 including some comparison shots with other UMPCs and slider devices. It’s interesting to see that the original Everun is exactly that same size as the Eking S515 but provides about double the battery life. The Eking S515 is slightly faster and has a better keyboard but try using it in portrait mode!

I’ve included some screenshot images so that you can see how much information you can get on a 4.8 inch screen. Remember, higher resolution doesn’t mean more space. The physical size of a font has to be the same on every resolution in order to be readable.

And here’s my favorite image.
