My device seemed to respring on it's own but everything looked as it should and I got no pop up message indicating my device had entered safe mode as I would with previous JB on iOS6. However, all my tweaks were clearly disabled and not functioning at all. Some of the preferences in Settings, when viewed, were blank or missing. I did a power down then turned back on and everything seemed to be working. It effectively seemed to be like "safe mode" but I got no message about it. Can anyone confirm if there is an on-screen message indicating you have entered safe mode with iOS7 JB?
