Huh, I could not find the answer in this thread either, but I did find this on the XDA forums. A couple of apps to fix the "number of texts sent in 30 minutes" issue
If you want to edit the settings manually, check this page of the thread out. Use SQLite to edit the settings.db
Yea - thanks.
No issues w/ texting too much - just looking for a fix for the sound issue.
