If u have bluetooth on your phone & a computer(also w bluetooth) then u have such an easy task. U just need to make both devices discoverable(open up bluetooth on your phone or comp) & it will give you the option of entering a passkey(1 that you make), you enter the passkey to the other device & now you can send ringtones to your phone. If you do not have this then you may want to try a ringtone pgm that will allow you to send it to a network & that network sends it back to your phone. Or you can find a store where you can purchase ringtones from $1-$2 if the previous suggestions seem a bit much
