This silly problem about 'sync' has certainly bothered me since a long time:
What do you mean by "Sync the iPhone"?
I used to get confused when doing such stuff because I do not know if my Mac has data A, and my iPhone has date B, to sync them will mean to make Mac have the exact 'B' or 'make the iPhone have the exact 'A'?
For example, I took many photos in my iPhone, and never know how to get them out with this 'sync' functionality, because my Mac has no photo and if I understand the wrong way and do the sync all my photos in Mac would disappear, right?
A similar scenario is my Mac stores some mp3, and I truly hope to use 'sync' in a safe manner to copy the mp3 from the mac to the iPhone. Yeah, I know it is quite a stupid question. Finally I take the courage to ask.
Can anyone explain me about the semantics of 'Sync mac with iPhone' etc?
