I looked at this, how much is it again?
Any bugs/problems?
The thing I might not like though is, so I assume you make an event in calendar to trigger a profile, say a work event running 8-5 to be in silent mode. So that means 5 events that have to sit on your calendar? Does it still work if say I make a "profile" calendar and tell calendar to not show it?
No, if you want to create a repeating event (say for every weekday between 8 & 5), you just just need to configure it in any event and it will stay there even if you subsequently delete that event. It's not the most intuitive interface, but it works.
Although, ever since I installed it on Sunday, I'm getting 3 or 4 springboard crashes each day. Although I also installed a lockinfo update recently.... who knows.
