Hello,
I just received the notification, that there is in AppWorld an update available for one of my applications.
After checking the details, it is an update to BBM !
If you don't use any leaked versions, and want to stick with official releases, then just go and get it :)
In case it does not show for you, after logging into you account reset it (press ALT and R+S+T)
After a while the AppWorld will close, and once you open it again it should refresh your account.
