3 quick (newbie) questions

[bobby yarrow]

Thanks again to you folks for the great help and kit on this forum. 3 questions that (I think) should be quick:

1. I recall that there was a setting - in one of the tweaking apps maybe? - that made hitting the X to close a program actually shut the program down. Had before I flashed my ROM, and now I can't find it.

2. I switch back and forth among silent, vibrate & normal a lot. I feel like I must be missing something obvious. Is there a profile app that just lets you switch sound profiles quickly?

3. Flashing the ROM was easy, as you know, and I have a feeling I'll be doing it again. Is there any way to back up my email account settings (or any other preferences really), or do they need to be entered each time? I don't use USB sync, use an exchange server connection.

Many, many thanks.
