Seeing as I am not a germophobe nor do I treat my phone as a sacred artifact I'll continue to use paper towel, my tie, shirt sleeve or whatever else is lying around. This "tip" is just way over the top.
I use the liquid spray eyeglass cleaner that Costco sells. I spray a little on the cloth provided with the cleaner and wipe my BlackBerry down every single morning, just as Mike does. I'm rarely sick! And Costco refills the bottle of cleaner for free!
Sometimes I use the (alcohol) pre-moistened towelettes you can buy for cleaning eye glasses. They seem to have just the right amount of moisture. Not only do they clean your screen and keyboard but I suspect the alcohol disinfects as well. Sometimes I just use a dry microfiber cloth.

Wont affect me, just trying to help the community.
If it works for you then that's fine. Don't worry about what anyone else has to say as it really doesn't matter. Just continue to do what works for you.
