Synchronization
Synchronization allows you to save your calendar and contacts data on
a remote Internet server (network service) or on a compatible PC. If you
have saved data on the remote Internet server, you can synchronize your
phone by starting the synchronization from your phone. You can also
synchronize the data in the phone contacts, calendar, and notes to
correspond with the data of your compatible PC by starting the
synchronization from the PC. The contact data in your SIM card is not
synchronized.
Answering an incoming call during synchronization ends the
synchronization, and you must restart it.
