A really useful application would be a locations-based setting application.

For instance, if it knew you were at home based on the wifi network you're using or your location, it would be nice to be able to automatically set call forwarding to your home number

Or, if you're at work, it would be nice to be able to set your phone to vibrate automatically, etc, etc

Bump! I second this too!

This would be a great IDEA!
