I recently created a "Hail to the Redskins" ringtone for my phone and wanted to share it. I converted it into most of the common ringtone extensions (.aac, .m4r, .mp3, .mp4, .ogg, .wma) It's total run time is approx 16 seconds.
For those of you with an iPhone, sorry the .m4r wasn't working. Here's a new link. Download the file, connect your phone to your computer and then double click the .m4r. iTunes will automatically add it to your ringtones library.
