Step 1:
Login to your Facebook or go to facebook Developers page.
Step 2:
Now you see the same screen you saw when you were activating your Facebook Timeline but this time you will click “Edit App” instead of “Create NewApp”
Step 3:
After clicking Edit App you will see the same app you build when you enabled Facebook Timeline
.
Step 4:
On bottom left of your screen there will be an option to “Delete App” click that
.
Step 5:
Facebook will now confirm whether you really want to delete this appor not, click Confirm.
Step 6:
After clicking Confirm you will get a confirmation pop-up that your app has successfully been deleted, click “Ok”
Step 7:
And that was it, you just disabled Facebook Timeline, go back to your profile and youwill see your old Facebook Profile.
Method -2
This trick is only available for Firefox users.
Install User Agent Switcher.
Restart your browser.
Goto Tools-Default User Agent-Internet Explorer-Internet Explorer 7
Refresh your Facebook page, now you can see your old profile
This happens because IE7 doesn't support Timeline.
