Getting new iphone on your itunes account, how?

Just wondering if you buy a new iphone and already had itunes with an ipod can you get all of your music and stuff on your new iphone or will i have to make a new itunes account?

I believe so as long as the music is on iTunes on your computer just plug up your iPhone it should sync after it does that just drag and drop the music onto your iPhone

Ya when you set it up it asks if you want to use an existing itunes account or new one just click existing one if music does not show up on phone plug it into a computer with your itunes account on it and sync the music on manually but if you pick existing itunes account all must should show up.
