This procedure must be repeated for each notification in hand, so if you have several such messages unread, will be a bit difficult.
It is a very simple tweak that can be used for many useful sites that iDevice users have, of course, the new IOS 5.x installed. Ipsum is available for free in Cydia BigBoss's repo.
