The timeout behavior I describe is only for the Droid X model. For instance, I'm told that variants of the Galaxy S series (e.g. T959) have a 30s delay every 5 tries, but no limit on total tries. That would be a little easier than my 13s/try scenario above: (30+5*3)/5=9s/try, or 13 hours average crack time. Regardless of whether your device has a limit on total attempts, you ought to be aware that the security of your lockout resides not in the complexity of your pattern, but rather in a subtle facet of your phone's volatile->nonvolatile memory transfer timing.
