what service are you on?
I'm on voicestream (8890) and I can just go to their webpage and get any of them sent to me (but they aren't free, they are $1)
the cost isn't much, but useless to me since I just keep it on beep and vibrate and try to get it before it goes too long. I fucking can't stand when songs go off forever on someone's phone. it is like they are trying to show off what ringtone they have like I care.
