Hey everyone, is the dock required for charging and syncing? On the Apple support site, it says that I should be able to both charge (via AC adapter) and sync the iPhone with just the USB cable. When I do this, my powerbook won't recognize the phone. When charging with the cable straight to the phone and wall outlet, I don't see any indication that it's charging. Both processes are normal when the dock is used. Something wrong or is this normal?
