Ha ha, no, that SO post wasn’t mine.  But it looks like the same answer would apply to both of us.

I’d have to do a little research to figure out how to change the metadata.  Unless you can tell me quick.  Unfortunately since I don’t have any old “dumb” phones on hand that support 3GP but not the newer formats and codecs, I can’t really test if that would work.
