Each of those, I can check simply by sliding the "unlock" slider.
The daily event isn't really relevant because all events will alert me anyway (because they beep when it's time to do it).
Mail again isn't very relevant.. I'm mostly at a computer all day, I have email open anyway.
The weather I just don't care about.
Apologies for sounding argumentative / etc, I don't mean to! I am merely pointing out that I want to do something cool with a Jailbroken iPhone, something I can't do with my regular iPhone. Else I'll pass. :)
Ah, well, it doesn't make it magical, it just makes it more useful... For example, my lock button is broken but I can shake to lock it. Otherwise I would be out of luck.
