Palpacino,
It's a solid theory but I don't have that app installed.
However, I have seen another case of the "software sabotage" that you mention...a few days ago I installed the Slacker radio app and not even the next day all my sd card got mysteriously WIPED clean. 12 gb of music and some pics I had taken with my new droid were GONE.
It was on this site, actually, in another thread that someone mentioned slacker radio was the most likely culprit. It seemed like a good plan for slacker to basically delete all of your music so you have to dl an app to get some tunes. Not sure if it was intentional or not, but if it was, it's quite clever!!!!! I'm a developer by trade and I'd never go to such lengths as to "invent" a need for my product, but I guess that's a jumping off point for an ethics conversation which I'd rather not have. Talking about the droid is a lot more interesting.
