By making one of the small changes that make our lives easier, Google announced today the open standard support for CardDAV, allowing easy synchronization of contacts with any operating system compatible with it. CardDAV joins CalDAV, which offers the same service for calendars, and iMAP.
Users wishing until now to synchronize mobile devices could choose a detour by using Exchange ActiveSync protocol.
For example, iOS users who otherwise are the main target audience of the new CardDAV support, can choose to synchronize their Gmail messages or using Gmail profile, if they lost their sync contacts or by using their Exchange profile, but limited by the method of the maximum number barrier and the nature of additional fields permitted by the Microsoft protocol.
With the new protocol, iOS users (and others) will be able to enjoy a full synchronization of all the data in the directory, but they must run versions 5 or 6 of this operating system. Google also offers a tutorial for this type of account activation.
There are also important limitations: as if CalDAV service does not offer a Push type synchronization, so updates will be made only at the time the application for contact is opened or scheduled intervals for Fetch. Choosing between limited but automatic synchronization with Exchange and complete but scheduled update via CardDAV is up to the user.
