I have a macbook and an iphone. Id really like to keep the phone synced as much as possible. But as I need to charge the phone every night, I use the charger/ dock, and syncing does not happen as much as it should. Im wondering if I can charge the iphone with a powered hub, so when the hub is hooked to my computer it will sync, but it will also charge at night when my computer is not connected. I just dont want to have to disconnect my cable/ dock just so I can sync it. Thanks.
