So this just happened to me, and I don't see any way I could've accidentally done it. I really hope I did it, but I just don't see how. The last thing I did was check an email, then relock the phone. I picked it up again and went to unlock it. Nothing happened. I kept trying, but nothing. Then I held the power button and it started booting up. This is the first time I've had any sort of issue. My battery is at 40 percent remaining after SIXTEEN hours, so I know it's not a dead battery. These are the changes I've made since yesterday: Started using LauncherPro and NoLock Disabled Sense weather sync since I can't get the animations with NoLock anyhow That's it. I hope it was just a fluke because, like I said, no other issues whatsoever.
