My (ancient, crappy, cheapest-could-buy) phone sits in my (courier) bag, where I can't hear it ring, so never answer it. Suits me fine. I do use a pair of Grado headphones though, I love the retro look, and they sound lovely. And since they are uncommon over here in Australia, they help me look down on people with clichéd Sennheiser or god-awful Skullcandy headphones. And headphones are almost a necessity since I just moved and gave myself a 2 hour each way train commute.
I'm guilty if having a few courier bags as well. My excuse is that I'm still going to university (albeit as staff, not as a student). I use Crumpler bags, a bit expensive, but Australian (sort of, if made in China counts).
