Apple iPhone 4

iphone

With a revamped design, a sparkling new display, a speedy processor, and additional features, Apple iPhone 4 is the biggest upgrade to Apple's smartphone since the iPhone 3g. It's also the showcase handset for Apple's newest operating system, iOS 4, which adds a selection of long-overdue features, plus a selection of smaller tweaks that we weren't expecting.


If they existed independently, iPhone 4 and iOS 4 wouldn't be much more than blips on the smartphone radar screen. When combined into one handset, however, the result is a sleek, satisfying, and compelling device that keeps Apple strongly competitive in an increasingly crowded marketplace. Indeed, the iPhone 4 is fast, the new hardware is a looker, and some of the new features blew us away. On other points, however, we have some concerns. Call reception still has its problems, and though we welcome multitasking with open arms, it has its drawbacks. Also, though the FaceTime video calling is more than noteworthy, we wonder if our interest will last more than a week.


So should you buy it? If you're an iPhone fan, you've probably already ordered your new baby. But if you're on the fence, think carefully. We won't say that the iPhone 4 is the best smartphone on the market today. To do so would ignore so many great competing handsets, and the fierce rate of change in the technology world. If you prefer Apple's vision of a polished, highly organized, and slightly closed user experience, then by all means you'll be pleased. But if you prefer a smartphone that offers more personalization, that isn't shackled to AT&T, or that is equal parts phone and mobile computer, than there are plenty of smartphones in the sea.


The iPhone 4 is available exclusively with AT&T and with other carriers around the world. With a new two-year contract, AT&T customers will pay US$299 for the 32GB model or US$199 for the 16GB version. Without a contract, you'll pay US$699 or US$599, respectively, but the phone will still come locked to AT&T. The iPhone 4 goes on sale in the US, France, Germany, UK and Japan on June 24. Australia, Austria, Belgium, Canada, Denmark, Finland, Hong Kong, Ireland, Italy, Luxembourg, Netherlands, Norway, New Zealand, Singapore, South Korea, Spain, Sweden, Switzerland will get the iPhone 4 in July.

Conclusions:

The good: Improved performance; lovely new display and an improved design; adds a ton of sorely needed features, both by itself and through the iOS 4 update.

The bad: Multitasking entails some trade-offs; home screen folders are limited to 12 apps; AT&T reception continues to be spotty.

The bottom line: With iPhone 4, Apple again shows that it's a powerful player in the smartphone wars. It won't be for everyone, and AT&T remains a sticking point, but the handset's striking design, loaded feature set, and satisfying performance make it the best iPhone yet.

CONCLUSIONS

The good: Speedy performance; gorgeous 4.3-inch Super AMOLED Plus display; lightweight; good camera; TouchWiz interface is easy to use.

The bad: Social Hub doesn't work well with Twitter; short battery life; flimsy back cover.

The bottom line: The Galaxy S II is quite possibly one of the best Android smartphones released in 2011, though it is not without flaws. That said, it is a handset that improves on its predecessor, the Samsung Galaxy S, by leaps and bounds.

Review:

First announced 2011 in Barcelona, the Samsung Galaxy S II is the sequel to the wildly popular first generation Samsung Galaxy S smartphone. For most Android lovers, this is probably the Gingerbread (Android 2.3) smartphone they've been waiting for. Let's see what this high-end product from the Korean chaebol has to offer.
