With the app "wheres my droid" you can set it up to ring in silent or vibrate no matter what when you send a text message to the phone that matches the text that you have your phone set to ring in the app. What I need is the same thing, but ring when the phone is set to vibrate or no ring when a particular phone number calls the phone. Basically the same app, but I need it to work when a certain phone number calls and not the texting part. Any out like this? Or would this be a good app for someone to make.
