One day in the Eris forum, I stumbled upon those popular "DROOOOOIIIIDDDD" notification ringtones. Once I heard it, I told myself I just got to have it. I downloaded the notification ringtone and put it on my phone. Just one problem, the stock ringtone picker cannot detect it! I browsed Google and found this app, Tone Picker - MP3 Ringtones. This application allows you to set downloaded ringtones off the internet as your ringtone or notification ringtone. Just open this application, click Default Notification, and click Select music track, choose your song and boom, your notification ringtone is now "DROOOOOIIIIIIDDD!" This application also has nice volume sliders for the ringer, music, call, system, and alarm. You can easily change the volume for each item. This is a fantastic application and I highly recommend this to everyone!
