What about changing profiles if phone finds your home/work/school wireless connection?
This way if you come to for ex. work, it searches for wireless connection, finds out that you're on work and changes your profile to silent. When that wireless connection isn't present any more it switches your profile on the one you had before you went to work.
This can work too when you're leaving home and home connection isn't accessible.
It should have infinite modes that user can make.
Here are some ideas for other parameters:
- Time
- Location
- Battery
All the parameters should be mixable. I think this could work for applications too. Sorry if this is too much off topic.
