[csturek]

I read at a palm site that a user was looking for an app that he heard about that went likethis.....u r in a loud place, ur fone rings , u answer it to not miss the call but the guy on the other end cant hear you or you cant spealk yet cuz u have to get out into the hallway ...the app picks up and ur prerecorded greeting says....i have just answered the call and am walking to a quiter locale to take the call hold a few seconds or something like that...
where can i get this?
