My LG GW520 should have a facebook app. but doesnt. How would i go about getting one?

[Matthew U]

I got an LG GW520 for Christmas today. I love it, but I was told it had a facebook app/widget so it could be quick access and better but this is missing. How would i go about getting this? Is there a site i can get it from or would i have to go back to the Orange shop?

Cheers and Merry Christmas!
I have seen videos with the widget on, clicking the button above the blue dice. But mine isnt there. Any ideas?
^^ in responce to Imhereforyou
Actually, is there anything i have to set up on the phone to get this widget avaliable too, or should it be there automatically? Because ive dragged out all the widgets and there is no facebook one 'blue one with a large F'
