If you use Google’s services for email, calendars, and contacts, you're probably aware that there are several different ways to access your data. You can use your favorite browser to access the Web interface. If you prefer dedicated Mac or iOS client app, you can use any that work with the industry-standard IMAP or POP protocols to access email, with CalDAV to access calendars, or with CardDAV to access contacts. On iOS devices, you've also had the option of using Google Sync—Google’s implementation of the Microsoft Exchange ActiveSync protocol—for all those kinds of data.
