Hey Sis,
First, I have a droid x, so I'm not sure if this'll work for you, hope it helps though.
I bought an app called Recordoid, you can get the free version from the market and have follow the link to the Developer's website for the full version. The reason I chose this app is that it allows unlimited recording, and has an option to save the recordings in .wav format, which is more common than the .3gp format, plus it looks like an old tape recorder. I recently found another one called Livo (like Tivo) that costs about the same and has a little more functionality for more technical people. I would try both free versions and see which you like best. If you start the radio and have it play through your phones loudspeaker, then start the recording app, it will record what it hears basically. The downside is that it records EVERYTHING it hears. My phone has a mic right next to the speaker so I get decent quality. here is a link to the full version from my phone for ou to try this weekend if you want, if it works for you, it will be worth buying.
