RE: "Instago" Instagram app ready for mid-March be I understand that one of the reasons for the delay in Instagram app , is that the company, owned by Facebook, has only a relatively few employees (I 've heard 20 or so) and they are working all out to do it. At any rate, I found this article about the so-called Instagram flap which gives some insight into the situation. Naturally, I think Instagram on Blackberry Z10 would be a win-win situation. I know the kids love Instagram.
