Como recuperó mis tonos

If you mean redownload them then tones are a one-time only download from the store. If you no longer have them on your device then sync them back from your computer's iTunes library. If you haven't got a copy of them on your computer nor backup of your downloads/library then try contacting iTunes Support and see if they will grant you a redownload : http://www.apple.com/support/itunes/ww
