I just got a new MacBook Pro and transferred all my music/movies/apps onto it. However I haven't synced my phone to it yet. I'm worried something will go wrong or all my apps will be rearranged which I really don't feel like dealing with right now. Before I go and sync it does anyone have any advice? What should I expect? Once I sync it, can I choose to sync it to either computer? (whichever is more convenient at the time?)
