Is there an auto-reply/auto-attendant app for SMS on iPhone4S? I'm looking for one that will automatically send a reply without the user having to manually press to send the reply.
My boss is going out of the country for a month and will not be taking his iPhone. Because he received a lot of SMS messages from our clients, we're looking for an auto-reply app that will send them a customized message that he's not available so they don't think they're being ignored. His phone will be off.
