I've never seen solution number 1. I'll have to look for it, as I might be able to find a use for it. It doesn't quite fit me, though, as I have a variable idea about who I want to talk to and who I don't.

I actually have solution number 2. The problem is that the one I've got doesn't have a backlight, amongst many other UI errors. (By the way, don't buy Sony telephones. They're just not good for a variety of reasons. I ignored my own advice on this the last time, and I paid for it.) I obviously could get a better phone, but I figured if I was going to do something to solve this problem, I might as well go whole hog.
