I was using an app to send messages to growl if i got a text message, and it had options about turning on bluetooth if it wasn't already on. But it wouldn't turn it off after "notifying."
Darn gremlin still infecting my DroidX. Have checked all possible nooks and crannies of my Droid and still, still, still my bluetooth keeps turning itself back on, usually about 3-5 minutes after I turn it off.
