with iOS 4.2.1 without having to update to 4.3.3? Like any tweak in Cydia to trick it into thinking it's running 4.3.3?? Any help would be appreciated
no there is no tweak for that. there might be one that tricks itunes into thinking you upgraded. however this won't fool the app. that is like you running apples Tiger and wanting to run a program that requires leopard to run.
