Blackjack Pda

I have software at home that I bought at Best Buy to make my own ringtones. and when I send to my phone, they go in my media file. So when I try to transfer the work does not work.
and there is no button for me "Set as ringtone" or something like that. can not receive the PDA phones ringtones? they must be purchased through my carrier?

You can select any mp3 or wav as ringtone
