does anyone else's touch sometimes jump back to the home screen when you unlock it? Mine will do it at random - I only notice it when I was playing music earlier and it jumps out of the iTunes app.
Never happened to me on either my 1g or 2g. It should only do it the first time you unlock it after syncing, as it automatically resets everything to the home screen.
Never had that happen on my 2G. Although sometimes resource-heavy apps will crash, and it will kick me back to the home screen. But other than that, I've never had it do that on an unlock.
