KB24962 How to enable and configure Places in Facebook for BlackBerry smartphones
"When setting up Places on Facebook® for BlackBerry® smartphones, there are a few steps that must be taken to allow the application to find your location and check-in.
It is important to note that by default, the option Share my Location with Facebook is disabled (unchecked) and may also appear as a non-editable/grayed checkbox. This option will remain grayed out until the application is able to determine that you have allowed Facebook to use Places and you have accepted the Places disclaimer"
Let us know how it goes!
