So here's a new one I haven't seen mentioned:
Since PB drains the life out of my battery, I try to do only a couple of apps per day. Last night, I scanned Calendar Snooze and it found 2 errors. I fixed the one that sends my phone identity, since I don't think a calendar snooze alarm needs to know that info, and reinstalled it. Today, my phone was acting odd, so I rebooted it, and it went balistic.

It restarted and vibrated non-stop so I did a battery pull and the same thing happened, but I let it play out. When it finally stopped vibrating, I saw a warning in my notification bar that an illegal app was detected. It finally went back to normal, but left the Calendar Snooze icon in my notifs bar. When I drag it down, in big bold letters, it says "ILLEGAL SOFTWARE DETECTED, a illegal version of calendar snooze is installed". I can't get rid of it. I don't know how the app knows I messed with it, but it does. I'll go back to the stock version, but wanted to let you know. Very odd!
