Enable Facebook New Timeline using Developer Hack
It is possible to activate Facebook TImeline using the developer hack by just creating a developer hack and choosing Open Graph Settings.
1 First go to Facebook Developers Page.
2 You might have to sign in again even if you are.
3 Create a New App. Enter the application name and a name space. I figured it out later what I as doing with name space was wrong.
4 You might have to enter verification code.
5 Namespace should be always in small not in caps. I guess facebook should auto convert this.
6 Done that, Go to Open Graph
7 Now Add a Action and Object. Like TImeline and Facebook
8 You might get some error, keep trying or skip to see if the actions and objects got inside.
9 Now go to dashboard and edit some settings here and there.
10 Now if you visit your Facebook Page, An Invite should be waiting for you.
