iPhone ideas, and does anyone know if this is available now or not?

1. when your phone auto-locks after 30 seconds or five minutes depending on which setting you have it on...if you are like me you have it on 30 seconds so in case it is lost or stolen they cant get into it, but 98% of the time you are at home, especially now, and this is not an issue...so how awesome would it be to have a setting that allows you to change it to 5 minutes for instance but then it automatically goes BACK to the 30 second setting 30 minutes later or an hour later...

2. to make the red 1 go away from a TEXT message you have to open the text message, most of the time I dont need to open it to see what I want to see but I always want that red 1 to go away...I dont suppose there is a way to do that? To be clear, anytime you get a text you can see it in preview or whatever but to make the notification go away you have to click on it and go into messages to see it then go back out...
