I've seen many screenshots showing a mail symbol in the status bar. What tweak is this?

Thanks!

I had to search on Google since no one else would help.

I found OpenNotifier, iOS 5, or IntelliScreen X.

Yuck.

Why would I want this? I'd always have a little mail symbol staring at me, making me feel guilty for something I wasn't attending to.
