The SX1 comes with a full-featured address book so you don’t have to remember all those details.

Store address information, phone numbers, e-mail addresses, job title and other information in your SX1. Synchronize the information with your PC so you can always be organized. 

Voice dialing
Voice dialing allows you to dial a phone number by simply saying a word (for example, the name of the entry). To record a voice tag, select an entry from your contact list. When you want to call this person, just press the Voice Dialing key on the phone. After a  short signal sounds, say the Voice Dialing name to call the person. Use voice dialing up to 30 phone numbers.

Groups
You can assign a large number of Contacts entries to a group. These groups can be used as convenient distribution lists to send short messages or e-mails. You can also set a specific ring tone for a group, so the ring tone plays whenever a group member calls you.

Add a picture
When you add a picture to a Contacts entry, the image is shown on the display of the SX1 whenever the Contacts entry calls you.

Business card
Create a customized business card entry and transmit it via SMS or e-mail. You may also transmit it to another device using the Infrared or Bluetooth capability.
