Comment 2 for bug 539676

I'm not sure the term 'instructional text' is correct. The linked wiki page shows both the devices and services tab with a small descriptive text, such as what the devices tab shows now. The devices tab's text should be slightly different, and the services tab needs to have that label too. I'm not sure the omission of such a text on the accounts tab is correct (will check up with the appropriate people, but it doesn't change the essence of this issue).
