1. What is being synched when using WiFi synch? Just my app data? Does it also synch images and videos? 2. I have plugged it into a wall and it does not seem to by automatically synching. Is it supposed to auto-synch each and everytime it is plugged in? 3. I just checked the iPhone and it says on the synch screen that it will resume when the Macbook Pro is available. What does that mean? Both the Mac and iPhone are on the same network. Thanks!
