CrackBerry just posted a work around for being able to log back in to Instagram on your BlackBerry 10 device. A lot of users who had not yet installed it, or logged out were getting an error stating they had to update their version. It seems that you can trick the system in to letting you back in by resetting your password via Facebook.
- Open Instagram (you can download the .BAR here and learn to side load it here)
- Choose Login
- Select ‘Forgot Password’ then select reset via Facebook
- Log in to Facebook and choose a new password
- Et Voila, you are back in!
