I did manage to get the Sound Recorder working, and its interface for recording is exactly what she needs. Unfortunately, there doesn't seem to be any kind of interface for playback, which leaves her at a loss.
Leatherneck, her phone isn't rooted. I'm sort of keeping it as the control in our little home Android experiment. If she *really* feels like she needs this app, I may just bite the bullet and do it, but I'm hoping that I can just convince her to use something else.
I think my best option is going to be to download one of the crappy free sound recorders on the Market and just cross my fingers for Froyo sometime within my lifetime. Thank you both very much for your help.
