I used redsn0w_mac_0.9.10b2 to jailbreak my itunes-restored iPad 1. All was well, except that iBooks, the appstore, and itunes apps crashed when starting. I again used itunes to restore the iPad and then used redsn0w_mac_0.9.10b3 to jailbreak. The same issue with iBooks, appstore and itunes apps crashing at startup continued. I tried many of the iBooks fixes circulating on the net, but none worked. Otherwise the iPad functions normally and syncs with my mac's itunes without a problem. What's up with iBooks, appstore, and itunes apps crashing on the iPad 1? Anybody know how to remedy this?
