Too late. Apple has already responded and revoked the signing certificate this app uses. You will have to change the date in order for it to keep working.

Yeah, it says on the screen now that you have to change the date to before 19 Feb for this to work. But you only need to do this after a reboot. If you don't reboot, you only have to change the date once.

I figured I would grab this while I could sinse I am not jailbroken.
