I'm having some trouble with Mabilo Ringtones. I want to set a certain tone as my Default, but when I went to the App, and clickrf "Set As", then chose "Default Ring", I expected that when someone called me I would hear it. What came out was a Verizon ringtone, I think. Personalizing ringtones to contacts aren't a problem: just setting them as defaults are. I tried going to my "Settings" and then clicked "Sound" to see if I can set it up that way, but it wasn't available in the list to choose from. Help?
