I am running 5.0.1 jailbreak on my ipad 2 and i had a problem where my ibooks app would load up, the bookshelf would appear for a second and then it crashes. I deleted the app from my computer and then synced so the app would be removed, but when I downloaded it again on my computer and tried to transfer, I received an error stating that the app could not be installed. Right now the icon is on my ipad 2 but it won't load up (same problem as earlier). However under the "settings icon" on the springboard, ibooks is not listed as an app. Any help would be greatly appreciated. Thank you.
