I pwned my oldschool iphone with 2.0 so that I could have the appstore and be jailbroken. However with no more 3rd party support, i could honestly care less if I am jailbroken or not. I downloaded an app from the app store and it crashes at a certain point every time i run it, however the app seems to work fine for everyone else. I was thinking of just restoring the phone to a legit 2.0 via itunes and trying that out as a possible fix. I have tried removing and reinstalling the program with no luck, as well as restarting the phone with no luck. if I decide to just restore the phone with the official 2.0 do I need to do a dfu restore or just restore it normally?
