₦airaland Forum

Welcome back to BB10 rockers.
Please, I need help. No thanks to the loss of nairaland data, I would have gone through previous pages instead of asking these questions.
I just got my Z10 from Konga. It came with OS 10.2.1.2102 I wanted to upgrade it but it's telling me "you have latest software".
(1) Please, is that the latest version and if no, how can I upgrade it?
(2). I can't find Instagram in the application world. How can I get it?
(3) Also, how can I get android applications to work on the phone?
THANKS FOR YOUR ANTICIPATED RESPONSE.
