So you just upgraded your BBM to latest version 8 and it starts hanging. It hangs so bad you can’t chat or do anything meaningful with it. Below are links to downgrade your BBM back to the older smoother version. Simply click on any of them, BBM will be downloaded directly on your device.
Please note that this is for legacy Blackberry users. Also make sure to select the appropriate link for the software version you’re using. To check your software version, Go to Settings > About> The details will be shown there. Or open any text box and type ‘myver’ and press space key (without the quotes).
