Anyways, to set mp3's as your ringtones simply upload them and then while a song is playing hit the menu button and select "Set as Ringtone".

And now every song that you have done that for will appear on your list of ringtones whenever you go into change the ringtones on your contacts.

To make custom ringtones for your contacts simply go into your contacts, hit the menu button and select "Options", then "Ringtone" and from that list all the songs that you set as your ringtones will be listed.

Hope this helps!
