Why do my text message sounds keep reverting to default?

[AC Question]

Text message sound keeps reverting to default

I just got a Kyocera Hyrdo VIEW and, while I love the phone, the Messaging app (the one that comes on the phone) keeps reverting my text message notification sound to the default. I got the text tone I want to use from Zedge.

I just bought the same phone from Cricket and am having the same problem. Asked at the Cricket kiosk at the mall and they said to clear the app's cache. Unfortunately the Messaging app doesn't appear in the Apps list. Grrr-r-r-r--r-r-r-r-r-r-r-r-!!!!!
