Returning iPhone-What Do I Do With Cydia Apps????

[Foo4Everlong]

I jailbroke my iPhone 3Gs 3.1.2, and I am gonna return my phone to the Apple Store for a couple of reasons, but I downloaded the 3G Unrestrictor from Cydia, now I know I have to restore my phone, how can I save the 3G Unrestrictor app for later use? I'm assuming that iTunes will not backup this app. Thanks much. Later
