Pat has been trying to find an application that will allow her to customize ringtones for her mobile phone. Leo says that Ringdroid will do it on her Android device. Or she can simply copy her music to the ringtone folder and it will allow her to select it from there. She doesn't need any software at all.
The issue, though, is that Android's file structure is confusing, so the trick is to know where she's sending it to. A file manager called Astro will work. Another one is ES File Explorer. She can even use it to make a ringtone and it will do it automatically. She'll start playing the song from ES File Explorer, long press on it, and select "Make Ringtone."
