Does anyone know if the iPhone has an app (or otherwise) capable of setting up an away message/out of office message? I have searched on the forums, google, the app store, etc., but have come up empty handed. I'm pretty sure the Droid has an app designed for such (according to a friend) and some quick google searches. I'd love to see one developed if there isn't one currently on the market. The constant texting for my business during the day is starting to ruin my productivity (which is no good when you're a sole proprietor). Thanks.
