Is there anyway to get stuff from my iPhone to my new computer?

I've just got my new computer and want to get all of contacts/pictures/songs to computer from my phone. I don't want to just plug my phone in because I don't want to lose my stuff. Is there any way to do it?

You will not "lose it" for it will be copied into your PC. Have a read up in your PC book and iPhone book. Although you may not heve these if you bought second hand.
