I couldn't find this when I first got my Diamond last week, and it's an app that I really liked so I thought I'd post the cab here in VGA format for other new Diamond users.
You can download other VGA skins for the app here:

fyi: for those that aren't familiar, this app is a reset/powerdown app.
Mods feel free to remove if this is already linked elsewhere. Thanks
EDIT: Briggs found a newer version over at XDA. Everything works now as it should. Soft reset/Power Down/Screen OFF, and Hard Reset all work in this version. The newer version is the second cab posted. I left them both up in case someone still wants the older version. Have fun!
