As expected, the latest handset features a high-resolution display, a faster processor, and video calling, but it also sports unexpected additions like a new antenna and a gyroscope. It will be available exclusively with AT&T starting June 24. The price with service is fair--$199 for the 16GB phone or $299 for the 32GB device--and both models come in white and black versions. No, we did not hear a peep about the elusive Verizon iPhone, but we didn't anticipate any news on that front.

Design

The new iPhone's design is a sharp departure from the previous iPhone models. The front and back sides are glass, both surfaces are flat, and a stainless steel border circles the entire phone. Indeed, it looks very much like the photos that appeared on Gizmodo after an Apple engineer allegedly lost it in a Redwood City, Calif., bar back in April. Other new design elements include the aforementioned front-facing camera, split volume controls, two noise-cancellation microphones, and a new LED flash with the main camera lens. The iPhone 4 also switches to a Micro-SIM format, just like the iPad.

We welcome the new design elements on a couple of levels. The flat backside means that the iPhone will no longer wobble when it's resting on a table. Also, even though the overall effect is a tad boxy, the handset has a clean and unmistakeably Apple look. At 0.37 inch (9.3mm), the iPhone 4 also is 25 percent thinner than its predecessors. Jobs called it the thinnest smartphone around, but since that race changes daily, it may not hold the title for long.

We also have a small concern about all that glass. It is shiny and beautiful, but the glass attracts smudges by the ton and durability remains a concern. Jobs said that glass better resists scratches, but we hope that the iPhone 4 will take a few drops to the floor without cracking. On the upside, it feels solid in the hand.

Display

Apple has a unique talent for making us want something we never knew we wanted. The iPhone 4 features a 940x640-pixel (or 300 pixels per square inch) "Retina Display," which is four times the resolution of previous iPhone models. What's more, it uses the same IPS display that's found on the iPad with an 800:1 contrast ratio. Though we've always thought highly of the current iPhone displays, perhaps Apple wanted to respond to the gorgeous screens we've seen on phones like the HTC Evo 4G.

In our brief hands-on, the display is clearer than crystal clear (Brian Tong's words). Since it renders all text the same, we had no problems reading screens from a variety of sources. Photos looked especially lovely, particularly when you compare the same image between an iPhone 4G and an iPhone 3GS.

iMovie and iBooks

iMovie brings movie-editing capabilities to the iPhone. You'll pay $4.99 for the app, but it's a nice touch. iBooks also adds some nifty new features. You can make notes on pages of books, view PDF files, and sync purchases between your iPhone and iPad.
