No Jetpack widgets

Hey there,

I was fiddling around with an old WP-website of a friend of mine which I used to maintain (but kept updated).

I have Jetpack installed on it and wanted to put a ‘facebook like-box’ widget on the homepage. But I noticed I cannot find any of the Jetpack widgets in my appearence->widgets menu. I have wordpress and all of my plugins up-to-date including jetpack, I can see all other widgets (including my jiggoshop widgets) But I just can’t find the Jetpack widgets. I tried to deactivate and activate the Jetpack plugin, but this was also no use.

I wondered if this problem occurred to other people as well and if there is a solution for this. (I have the feeling I am overseeing something really stupid, just don’t know what it is).
