I have tons of questions, but I'll just ask the one for now. If I download any paid apps from Cydia, what happens if I have to unjailbreak? Or if I get a new phone in the future? Will I have to pay for all the apps again, or is there a way to back them up? I have AptBackup, but I guess I just don't understand how that would work if I ever have to completely delete all this stuff from my phone.
