I can't hide iBooks and I have followed the directions
iPad 2, iOS 6.1
You can't currently do it on iOS 6 - from the bottom of the iOS section on that page :
You currently cannot hide purchases on devices using iOS 6.
You should still be able to hide items on your computer's iTunes
Do you know if this will change soon
I don't know. It hasn't been possible since iOS 6 came out last September (I think that was when it came out), and IOS 6.1 last week hasn't changed it. If/when it might be possible to hide items again I don't know
Can I remove IOS 6.1
No, downgrading the iOS version is not supported by Apple
I can't hide my purchased books
