How to get status notifications from Facebook sent to my iPhone 3GS?

My friend has an iPhone 4 and he can get status updates through notifications from Facebook without having to open the app. I have went online and clicked the get all updates from the people I want to get notifications from but I still do not get them. Is there anything else I'm doing wrong?

You can try it out this app, Schedaroo.

It helps you to text updates to facebook at any scheduled time even.

I use it a lot.
