My iPhone's Lockscreen clock wont update without unlocking the phone I have an iPhone 4 running iOS 5.0.1.  It is Jailbroken, and the time on the lock screen won't update unless I unlock the phone.  My friend's phone is also Jailkroken (a 4S running 5.1.1) and she has the same problem.  

Has anyone else with this problem found a solution to it?  It is actually very incontinent and even annoying. 

I have ClockHide and AndroidLocXT installed.  I'm not sure if those have anything to do with the problem or not.
It's certainly to do with the modifications of the operating system. Either try uninstalling related mods or restore the device. This is not a problem you'd see with an unjailbroken iPhone.
And get that incontinence seen to :).
