I have my iphone set to manually sync with itunes because I want to be able to hook it up to any one of my computers at home or work and copy stuff to it. Unfortunately, the iphone won't let me do this, it says I'm already syncing with another computer! But yet when I check the other computer, it says it's on manual. When I try to turn the auto off on my Macbook Pro, the dumb thing says it's going to WIPE my iphone. So, now I can't copy videos or music to the phone from any computer other then my desktop at home. What to do?!
