Salesforce to Address Book App. No fuzz, no pain, just sync. Sync Contacts allows a one-way synchronization between your contacts in Salesforce and the contacts in the Address Book app of your mobile device (iPod touch/iPad/iPhone).
Your current contact list on the device will be neither modified nor deleted. A new "Contact Group" will be created in order to store/save your Salesforce contacts.
Sync Contacts works with Enterprise, Unlimited and Developer editions with API Access and does not require a mobile license. Team, Group, Professional and Force.com are not supported in this version.
Your Salesforces user needs to have access to the Security Token.
Please, verify with your Salesforce administrator if you have API access _before_ purchase the app ("API Enabled" checkbox on the Profile permissions page)
