I broke down and bought the upgrade for my iPod touch, jailbroke it, and set about deleting all of the iphone 1.1.2 apps. In the process, I seem to have rendered Maps on 1.1.3 unusable (crashes and returns to homescreen instantly). I have tried reinstalling 1.1.3 Maps and Maps prep, no luck. No idea what else to try (REALLY dont want to restore) anyone else know of a fix? Please? :-!
