Your issues are more to do with how Windows Mobile is set up then anything else...
For your first issue, if the phone is locked, it usually will still vibrate and/or ring if I have it set yo..
The second issue, you can just click ignore call and the incoming call will hang up. There is no hack that I know of that can simply do what you ask.. Sorry...
The third issue is just how Windows Mobile is.. You can go from let's say Notes, to Opera, then back again with out having to close Notes completely... But otherwise, it's just how it is...
If you have any other questions, please do ask
