Calling Features
The S66's built-in address book has room for up to 1000 contacts so you can quickly access email addresses, phone numbers and other info. Calling features such as call waiting, call forwarding and a list of calls received and dialed are also included. Meanwhile, the built-in speakerphone makes it easy to talk without having the phone to your ear, and the phone's Bluetooth connectivity means that your favorite Bluetooth headset is fully compatible. Picture and Ringer ID functions allow you to assign photos and ringers to specific callers. Polyphonic ringtones, as well as a vibrate mode, are also included.

Messaging, Internet and Tools
Powerful messaging and Internet capabilities can be found in the S66. While the phone fully supports text, picture, sound and video messaging, it also ships with AOL Instant Messenger so you can text chat on the go. You can get your email on the go, too, as the S66 has a POP3/IMAP4 e-mail client. With a Cingular data plan, the phone can be used as a wireless modem, providing internet access on your laptop or PDA. There's also a built-in web browser for Cingular MEdia downloads and mobile web browsing. Cingular's MEdia service lets you receive and send emails, read news headlines, get weather updates, download games and ringtones, and more. Traditional text messaging, as well as picture and sound messaging are also supported by the phone. 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 powerful tools ship with the S66, including a SyncML-based synchronization function that allows you to sync data on the device with Microsoft Outlook and Lotus Notes via Bluetooth, USB, infrared, or serial connection. Other tools include an alarm clock, a calendar, and a to-do list. There's also a voice memo function for recording notes and thoughts.

Imaging and Entertainment
With the S66's 1.3 megapixel camera, you can capture high-resolution (1280 x 960) images wherever you roam. There's also a 5x digital zoom for getting great shots from far away. While the camera is great for stills, it can also capture video in the MPEG-4 format. Video recording time is only limited by the amount of available memory space.

Java application and gaming support is also built into the S66. Many games and applications can be downloaded from Cingular's MEdia service. The phone also features customizable wallpapers and screensavers.
