iPhone 4S setup

Hello-

When I connected my new iPhone 4S to iTunes, I mistakenly chose it to backup from my iPod touch instead of "new iPhone". While I don't mind my phone having the same content as my iPod, I'm concerned that it has the same name (jmphoto's iPod) rather than a new name for my iPhone. I'm also concerned that the Bluetooth in my car won't recognize it now since it has the same name as my iPod.
