Design
The 6610 is designed to be easy to use, with large buttons and a generous 128 x 128 with support for 4096 colors. A large power button dominates the top of the phone, while a 2.5mm headphone jack and charging input are placed on the bottom edge. In addition to an infrared data port, there's also an input for Nokia's proprietary "Pop-Port," which is designed for Nokia accessories and USB data connectivity. A four-way control key controls most of the phone's functions and menus. And finally, the 6610 uses an internal antenna -- nothing to snag or break off.

Calling Features
The 6610's phone book can hold up to 300 contacts, with multiple numbers and text entries per contact. And because the phone runs on tri-band service (GSM 900/1800/1900 MHz) you can make calls from anywhere in the world. Meanwhile, an integrated speakerphone makes talking in any hands-free environment that much easier. You can jazz up your incoming calls with one of 20 polyphonic ringtones, and there's also a vibrate mode for those times when you want to keep things discreet.

Messaging, Internet and Tools
The 6610 features robust messaging and mobile internet functions. Traditional text messaging, as well as picture and sound messaging (MMS) are supported by the phone, as is mobile web browsing via a carrier-supported GPRS data connection. In addition to email connectivity, this lets you check the Web for sports, weather, stock updates, and whatever else you might want. T9 text entry, which is a technology that makes it easier for people to enter words and text on handsets, is built into the unit-- a plus for mobile email and text messaging users.

A number of handy software tools are bundled with the 6610 including a to-do list, a calculator, a calendar, and an alarm clock. You can easily sync up your contacts, calendars and other data with your PC using Nokia's PC Suite software, either wirelessly via infrared beam, or with a USB cable.

Imaging and Entertainment
While the 6610 comes with the standard custom screensaver and wallpaper features, there's also something extra: a built-in FM radio (stereo headset required and sold separately), which allows you to listen to your favorite stations on the go. The phone also comes with a few preloaded Java applications, including Converter II, Portfolio II, a Chess Puzzle, and a game called "Bounce."
