l have an iphone 4s, and now have an iphone 5s, l use mbpr using itunes to synch podcasts, mp3s and playlists to my 4s. l want to know if possible to transfer everything in my iphone 4s to new 5s? with everything l mean, apps downloaded, pictures, videos, mp3s, playlists and podcasts, contacts? if so how? is it as easy as plugging my iphone5s into my mbpr and synch or will there be another account?
