I'm on call a lot and need to know when I get an email. The little dings and dongs available as alert tones don't cut it - I might be asleep, or in the shower, or whatever. I need it to be persistent, annoying, loud, and not shut up until I acknowledge that I heard it. Unfortunately, this seems to be difficult.
I found an app in the store that claims to do it, but it only supports POP - I need Exchange. I'd rather something that hooked into existing notifications so I could use the normal mail client, but that seems to be impossible.
I can't be the only one with this need - does anyone know of a good solution?
