Anyway, I learned Lulu now made a sports bra with a pocket. I bought one this weekend on my way home from the DCAC fitness conference in Reston, VA. I just took it on my 7 miler this week and I LOVED it. It comes in very fun colors (to match their other gear) and it was very comfortable. The pocket is divided into 3 sections, so it is a smaller pocket overall than the Stow and Go by North Face. It held my ipod nano and a Honey Stinger each in a pocket of the bra just fine.
I bought the purple one: http://shop.lululemon.com/products/clothes-accessories/women-sports-bras/Run-Stuff-Your-Bra-II and I am very happy with the fit and color.
