…if there was a Mac app out there which would show a notification on your computer screen when you’d missed a call to your iPhone while it’s docked?

I was just thinking this today when having to leave my iPhone docked after it completely ran out of juice during the night. I haven’t been at the computer much today but have occasionally popped up to have a look at the iPhone screen to see whether I’d missed any calls. How convenient would it be to come up and see a Growl-style notification message on your Mac (that stays there until you close it) letting you know.

I would pay good money for that.
