yes i know this but when i plug in my iphone it asks me if i want to restore it from my ipod back up or if i want to set up a new iphone. im just afraid that if i set up as a new iphone i wont have any of my music i want.
If all of your music is on iTunes, then you can restore your phone as new and then sync what you want to it. If you want it to be a copy of your iPod then you would want to use that backup. Have you ever synced your phone to your computer?
