I upgraded to iOS 5 on my ipad. I used the latest RedSn0w to perform a tethered jailbreak and install Cydia. However, when I launch Cydia, Manage My Account, Featured, Themes, FAQ, etc all slide onto a blank screen when clicked. I have done a tethered reboot but get the same thing. Any thoughts? Nevermind. After a few hours it fully populated including all my previously saved SHSH's. The only issue now is that iBooks won't work.
