Hi, this has probably been asked but I have not found a good answer. I got a new laptop and want to switch all of my iTunes to it and be able to sync my iphone 4, ipad, and iPod touch. How can I change the new computer to be my main computer? I tried with the iPod and lost everything, so I am kind of scared to try it on my phone and ipad. What do I need to do to be able to switch laptops permanently? Any help would be appreciated:)
