Ever since the jailbreak, the wake function of my cover doesn't work if the iPad is locked. Per security policy, I have to have a passcode, and previously, opening the cover would bring up the keypad to unlock it. Now the screen stays dark. Once it's unlocked, sleep/wake works perfectly until the idle timer expires and it re-locks. Anybody else noticed this, or found a workaround? It's not a dealbreaker by any means and it's probably something I have configured wrong, but it'd be nice to fix if I could.
