I don't actually have a Galaxy S2 phone yet, however, I have a question to see if I can assist. Did she have the notifications setup on her previous phone? If not, then what she will need to do is log onto her facebook profile, select Account, then Account Settings. There will be a Notifications tab at the top, select that. Next, she will need to select each option that she wants to receive notifications for from her profile, making sure to check the correct option of Email or SMS. If she wants to receive notifications directly from the Facebook App on her phone, she will need to launch the app and then go into the settings option after possibly clicking the Menu button and turn on which options she wants to receive notifications for. Hope this helps.
