The bad news: There's a flaw in the Motorola Droid 2.0.1 software that can potentially allow someone access to your data even if you have a lock pattern set.
It seems that if your phone receives a call -- you can answer the phone without unlocking -- and hit the "back" button, suddenly you're in. No unlock pattern required. And that's bad.
The good news: For this to work, someone has to have physical access to your phone. Let's hope we see a patch for this pretty quick. And in the meantime, hold on tight to your Droid. [via The Assurer, thanks to everyone who sent this in!]
