I have an itunes account on my desktop computer and recently just setup itunes on my new laptop. I have the SAME ITUNES ACCOUNT (same user ID and all) on my laptop as I did on my desktop with all my music & everything transferred over to the laptop, but I was wondering what would happen if I were to sync my iphone onto itunes in the laptop? I have always synced my iphone with my desktop's itunes, but this time i want to sync it with the itunes on my laptop. Will my music that's already on my iphone be overwritten or something? Or could I simply just sync my iphone in the laptop and start putting more music on my iphone (from laptop)? Does my iphone recognize my itunes account or the original computer (my desktop) that I used? If there's a problem, how can I sync my iphone into my laptop safely so I can start transferring music to it again?
