I recently switched from Android to WP7 (and from Blackberry before that). There are only a few apps that I miss from my old phone. One that I'd really like to replace is a "profile" app what would let me set up profile names and associate vibrate on/ringer volume, and ringtones for various profiles. For example, one profile for at night, one for day, another for meetings. Does anything like that exist on WP7?
