The Good Great color screen; Bluetooth; megapixel camera with video; MP3 capable; multiple messaging options; solid call quality.

The Bad Bulky; inconsistent battery life; slippery keys; small phone book.

The Bottom Line Though the multimedia-friendly Sony Ericsson S710a has a solid feature set and an alternative design, it doesn't come together as well as it could.

Ever since Sony joined forces with Ericsson, the company's cell phone lineup has consisted largely of candy bar-style models. It wasn't until last year that Sony Ericsson first broke new ground in the United States with its Z600 flip phone. And now in 2005, the company rolls out its swiveling S710a. Clad in a stylish package, the otherwise hefty handset offers an impressive list of features and admirable call quality. The interface could use some tweaks, and overall battery life was on the low side, but the Sony Ericsson S710a should appeal to cell phone junkies. At $399, the price is high, but it should be cheaper with a rate plan.

Cell phones with swivel designs are gaining traction in the United States, thanks in part to Sony Ericsson, Samsung, and Kyocera. Dubbed the S710a and dressed in basic black, Sony Ericsson's new handset has an eye-catching form factor with a screen that rotates 180 degrees to expose the keypad. The mobile itself is relatively bulky (4.2 by 1.9 by 1.0 inches; 4.8 ounces), so it won't fit in smaller pockets. On the plus side, you're given an eye-popping 262,000-color display that measures a generous 2.25 inches diagonally. The screen is among the best we've seen on a cell phone, though it is vulnerable to smudges and hard to see in direct light. Also, on a related note, the backlighting time and text size can't be changed.

Basic black: The bulky S710a has a large screen.

Resting just below the screen on the swivel's hinge are the main navigation controls. While the menus themselves are easy to understand, we were divided on the overall design of the controls. The silver buttons are set far enough apart, but they're slippery and not terribly tactile. A five-way navigation toggle can be set as a shortcut to four user-defined functions, but we lamented the lack of dedicated Talk and End buttons. Instead, two soft keys place and end calls; you also get a Back button and a Clear key. We were glad to see that the front face easily swivels in either direction, but to make use of the navigation buttons, the screen's orientation does not flip. As a result, you must turn the phone over in your hand when opening and closing. Once open, the keypad buttons were large enough for big hands. But as they are set flush with the surface of the phone, it's difficult to dial by feel.

Swivel: The S710a's screen rotates to expose the keypad.

The handset's backside is styled to resemble a camera--a nice touch for a megapixel camera phone. A handy sliding cover exposes the lens and a self-portrait mirror, while the flash sits to the side. Opening the cover activates the camera automatically, but the swivel must be in the closed position. When the S710a is held horizontally (the display doubles as a viewfinder), the camera shutter button on the mobile's right side instead lies on the top of the handset--just as it would on a standalone camera. Also on the right side are the Memory Stick Duo slot and a volume rocker, while the infrared port and a nifty key-lock toggle are on the left side. A rubber door on the bottom of the phone covers the ports for the headset and the charger.

The Sony Ericsson S710a comes packed with features that should please more-demanding users. We're hesitant to call it a true smart phone, though, because it uses Sony Ericsson's standard OS. While that may be fine for some people, smart phone fanatics may find the interface too basic. The 582-name phone book is rather small, but it holds an impressive amount of information for each contact, and the SIM card takes an additional 250 names. In each entry, you can save five phone numbers, e-mail and Web addresses, a business title and address, and notes. You can also enter your own information on an electronic "business card," which you can then send wirelessly. Contacts can be stored with caller groups, or they can be paired with a picture and any of seven polyphonic (40-chord), one monophonic, or seven MP3 ring tones.

Store more: The S710a's memory card slot sits next to the camera shutter.

Organizer features are plentiful. You get a calendar, a task list, a notepad, an alarm clock, a timer, a stopwatch, a calculator, and a secure area for holding passwords. Other features also were attractive. The phone comes with a vibrate mode, text and multimedia messaging, a WAP 2.0 wireless Web browser, instant messaging, a voice recorder, support for POP3 and IMAP4 e-mail, an infrared port, Bluetooth, PC syncing, and a USB port.
