I've searched everywhere.

I once had a simple phone from metro pcs (sadly, i do not remember the type of phone) When i Received a phone call, i had a guitar ringtone set up. When Receiving a text message it was a piano tone. Both were ringtones stored in the phone when i got it. I now have a smartphone (still metro pcs) but the ringtones stored in the phone are different. It may seem like an odd request but does anyone know how i could find and download those ringtones? Or at least maybe the names of them?? They bring back memories to me And i would love to have them back. Thank you
