I recently jailbroke my iPhone 3GS using absinthe-win-2.0.4 and today I shut the phone off completely and restarted it because it seemed to be running very sluggish. After about 3 long minutes or so, it came back on but the applications I got from Cydia were no longer working. I haven't tried to reinstall yet but am curious if that is normal behavior? The phone doesn't seem to be sluggish now. I suspect it is no longer jailbroken because Cydia is not working either. What else might I expect? Is shutting off a jailbroken phone a no no?
