Filling in the category of "unexpected but kind of neat", accessory manufacturer DLO has released OpenFM. The application, which is available for free, functions as a web site and allows web-based and iPhone users in the United States to find top-performing radio frequencies in their area.

OpenFM allows users to search by zip code or city/state and pulls up results from an active database of licensed FM broadcasters. According to MacMerc.com, the program uses a set of algorithms to match the database's information against known locations of radio towers to determine the best FM frequencies to use. Returned results are categorized from "Best Bet" to "Good" to "OK".

In addition to the iPhone application, DLO has also announced that it will be offering a web-based version as well as a widget version of OpenFM for Mac and Windows in the coming weeks.

If you've tried OpenFM or similar programs and have feedback, let us know in the comments or forums.
