Thank you for contacting the Rogers Business Technical Support Center.
We appreciate the time you have taken to email us regarding your inquiry.
In reference to your email, currently Rogers Wireless Blackberry products are not optimised for the Facebook application. Hence, we are unable to provide a guarantee regarding functionality or performance as Rogers does not have a service agreement in place with Facebook.
While the application is generic in nature, each respective carrier has a specified version build based on carrier needs. Unfortunately the version offered by Facebook does not appear to be directly compatible with Rogers Wireless Blackberry products.
We hope this information proves useful to you.
