I have used many Facebook clients on my Nokia N8 and yet didn't find any better. Even the official client is very slow and difficult to navigate through. 'Fascinate' is one client which I have liked the most so far. The simple reason being that it is very fast and user-friendly. It even surpasses the Nokia's very own Facebook client as it supports advanced security features like, device identification while logging in. I cannot access my Facebook on Nokia's native client simply because I have the device identification feature activated in my security settings at Facebook. Even Facebook chat is integrated with this client.
It is very easy to navigate through the various features of Facebook with this client. Moreover, it allows you to slide through just like your multiple home-screens which means that you get more viewing area in a limited space. The swipe and slide is way too smooth and quick. The Facebook data gets updated real fast. It works in both the landscape and portrait mode and switching between the modes is quick. The image viewing experience on this client is best than any other I have seen so far. Fascinate supports push notifications and it can customized with a number of options. The theme of this application can be changed between black and the Facebook blue.
Once you have done installing the application. You need to allow permission for this application so that it can access your profile. This is mandatory otherwise the application cannot connect to your Facebook profile.You can download the installation file from the link below. The phone may download additional components during the installation process depending upon the pre-requisites available on your phone.
