Forgotten restrictions code?

Last year after Christmas my mom put a restrictions code on my iPod… And now she's forgotten it. She can't think of anything that she hasn't tried. But luckily, I'm getting an iPhone soon. Can I transfer all my music and pictures to my iPhone without the restrictions code? Also if I can't, then will I be able to download my music that I've backed up onto my computer from my iPod to my iPhone with a new apple ID?

You need to reset your passcode:
