This is mostly for 2.1+ iPhone/iPod users (2nd gen for smule apps).
Anyways, these are cracked apps :).
This is clean no viruses.
This wil automatically sync with iTunes when you double click.
Make sure your iPone is jailbroken, and you have cydia, add this source: cydia.hackulo.us, search miPatch, install it.
Get on app from iTunes store, and then you can add cracked apps :).
