The good news is that folks out there are hard at work to make it happen, and have discovered that only a single line of code blocks you from doing so. This is big because it means Apple could easily (and will likely) enable it in future versions of the iOS. The hack itsself can be downloaded from this Cydia repository: http://cydia.zone-mr.net
Will Apple move to block this in the future, or has the fruity company disabled the feature because of some unmentioned issue?
