Wondering if syncing is moving over the entire file to the local device, then syncing, or sending and retrieving individual items that have changed on groups of items?

Main reason for the question is if I am causing problems on the iPhone if I start syncing, and then press the home key, get a call, or interrupt the sync in some way. Does the iPhone app have to restart the sync from the beginning or has it made some progress?

Love to know more about how the syncing process works.
