Messaging app for missed calls?
I overheard a convo of someone discussing an app that sends a text message to a person who calls you if you miss their call telling them you'll call them back or i guess whatever message you set it to send.
Does this exist? I had never heard of it before, but honestly, that would probably be quite handy (especially if it could be set to specific contacts, and not just a general address book response to anyone that calls).
I searched the forum and google and came up with nada...info?
