I don't know then. It is a jailbroken phone so all bets are off. I don't have such a phone and so I cannot test TimeLapse on one. I have no idea what could happen on a jailbroken phone.
If you want to spend the time, you can un-jailbreak the phone (or run TimeLapse on another phone), and see if it works for you then. However, even then it would be difficult for me to really do anything about it as I don't have such a phone to test with.
