what I would expect. Have you got it on an auto update? some ads will slip through as the ad-servers (ie hosts) are changed intra-day. ie the "arms-race"
If you see an add on a web page, re-download your host list and reboot (I personally don't need a reboot to see the effects, your phone may act differently differently), then go back to the web page to see if that has cleared the ads.
