Jamilla S. from Marikina City DM'd TP this question via Twitter at around 8PM last night:
"TP, yesterday, I successfully installed Facebook app on my Blackberry Bold 9700. The problem is, since then, I haven't been able to log-in to my account using the app. It just keeps blocking all log-in attempts, stating that it's for my own security. TP, how do I fix this?"
No need for worries. Facebook app just wants you to verify that you are allowing a mobile device to access your account.
Since you have already tried logging in to your account using your Blackberry phone, you can just go on to the next step, which is to log-in to your Facebook account using a computer (laptop or desktop).
Once there, you will be greeted by this notification --
Just click on Continue button.
Enter Captcha Text.
Then, click Yes I Recognize it button to wrap up mobile access verification process.
Now, try logging in to your FB account using your Blackberry.
There, Jamilla. :) I hope this helps you.
