Tried this 100 times. Facebook app version 1.9.9, Gingerbread.UCLB3-- Facebook icon, settings, turn off vibrate and LED, turn on other sound. (there's NO WAY to save these settings) 10 minutes later vibrate and LED are back on. The facebook settings don't 'stick' and always revert back to the defaults. Is there a SAVE feature I'm overlooking?
