Finally, after passing countless scams on this, I've found the real deal. No surveys, no lies. But this is for Android: Messenger for BBM.
Interesting negative ratings/feedbacks for this app. I wonder if Blackberry is behind this charade. Not counting the scams.
If there's one for Android, then there's one for iphone. And that means writing such app myself is more possible now, if necessary.
I have a feeling this kind of good news may be gone soon. Capitalism conspiracy, who knows. So I best hurry.
