It has bluetooth, miniSD support and a pop-port connector. It can also play mp3's and aac's as ringtones.
What operating system do you have?
If your OS supports bluetooth, you can buy a bluetooth dongle and transfer things that way. Or you can perhaps buy a usb cable for it, but that may need you to use Nokia's software.
Thirdly, and my chosen way, is to use the miniSD card. If you have a card reader that has an SD slot (for your camear maybe?), you'll be able to use that for the miniSD card too. It should have come with an adapter.
