is there a tweak to put the clock back in the lockscreen status bar?

Hey Jessica, I am not sure about this, but you can try Cydia. I'm curious though, why would you need one? If the clock is on the screen you can see the time anyway. Not to mention the phone announces the time when you unlock it. HTH Kevan

Jessica, There is no need to unlock your device to check the time. To check the time, simply press the sleep/wake button and VoiceOver will speak the time. Alternatively, on the lock screen, the time appears to be displayed in the top middle of the screen. If you move your finger along the status bar to the middle, where VoiceOver says "Status Bar Item," move your finger below that point and you will reach the time. Another way to think about the position of the time on the lock screen is that it is directly below where the clock usually is when the screen is unlocked.
