Basic features include text and multimedia messaging, a notepad, a calculator, a calendar, an alarm clock, a stopwatch, a world clock, and a call log. You also get Wi-Fi, Bluetooth, a file manager, access to Google Maps, an internal search app, unit and currency converters, an FM radio, Windows Live Messenger, and a voice recorder. The W002 doesn't offer visual voice mail.
The W002's music player resembles that on the iPhone, though it's a bit crude. You don't get the cover flow interface and it doesn't even appear to show any kind of album art. On the other hand, it goes a couple of extra steps on the features side. In addition to shuffle and repeat modes, it has an equalizer and a selection of play sides. There's also a "lyrics display" feature, but we couldn't get it to work correctly. Of course, you won't be able to sync with iTunes, though you can load music on the phone easily using USB transfer or the memory card.
The camera's interface also takes a page from the iPhone's design, but like the music player it offers a few more features. Though the phone promises a 1.3-megapixel shooter, the four resolutions don't go above 640x480, which is only VGA. Other options include three image-quality settings, a night mode, a digital zoom, a multishot mode, a slideshow app, a self-timer, color effects, white balance, wallpaper frames, shutter sounds, exposure modes, and the flash. There's also a front-facing camera lens for self-portraits. Photo quality is mostly poor. Colors were a bit off and there was image noise.
The video recorder offers a similar set of options. You can limit clips to as short as 15 seconds, or you can shoot for as long as the available memory will allow. Video clips are nothing special; there's a lot of pixelation and the camera can't handle fast movements. The W002 has just 71MB of user accessible memory, but the microSD card slot can take cards up to 8GB.
For Internet access you get both a standard WAP browser and an Opera browser. The W002 also comes with a number of features like an eBuddy messaging app, three Java games (Bejeweled, LianLianKan, and Dice), an FM radio recorder, and something called a Books app. We're not sure what is does. Like the D8, the Duet W002 can get analog TV broadcasts (remind us, what's analog?).
We tested the quad-band (GSM 850/900/1800/1900) Duet W002 world phone in San Francisco using both T-Mobile and AT&T service. Switching between SIM cards is easy. After dialing a number, you can select the line that you'd like to use. Call quality on both networks was fine, but nothing great. There was an audible hum during calls, regardless of network and the volume was low. We also had a lot more trouble getting a T-Mobile signal. But voices sounded natural once we placed a call. Data speeds on the W002 top out at EDGE.
On their end callers said we sounded just average. They could tell we were using a cell phone and they reported a lot of background noise on both carriers. With T-Mobile, however, they also mentioned some static and a weaker signal. The speakerphone has a bit of distortion and the volume was low, but it mostly does the job. You'll notice that the onscreen commands while calling, and even the slider bar for turning off the phone, are very similar to those on the iPhone.
The W002 is rather sluggish at times. It took up to 3 seconds to open some menu items and to place and end calls. During those occasions we'd get a "processing" icon on the main display.
The W002 has a rated battery life of 3.6 hours talk time and 10.8 days standby time. We were impressed with the tested talk time of 6 hours and 47 minutes. According to FCC radiation tests, the Duet W002 has a digital SAR of 0.29 watts per kilogram.
