Those who have an untethered 4.2.1 jailbreak for their iPhone, iPod Touch, or iPad have found themselves unable to read books they have legally purchased within iBooks. Trying to open a DRM-protected book will produce the following error message: “There is a problem with the configuration of your iDevice. Please restore with iTunes and reinstall iBooks.” Deleting iBooks and reinstalling an older version will not help resolve this issue. Luckily, @comex has come up with a fix.
