I forgot you were on alltel. Forget the rename to orig (copy it somewhere safe on your SD card). If you can't copy it either I wouldn't worry about it. The one you have may be a ROM version only, which you cannot rename or delete. But you should be able to drop the new one with the same name on top (don't rename it to correct name after, drop the correctly named file on top). The old ROM file is still there, hidden under it. If that still fails, I'll upload the audiopara.cab file from Sprint phone, that may do some magic to unlock the file so it can be replaced. Then you can replace it with the patched ones.

No gurantees this doesn't mess up your phone and you end up needing a hard reset. I'm covering my butt and trying to help. But it's highly likely you should be fine experimenting here.
