Way back when Vodafone was J-phone, you would often get no user-agent
header making detecting these buggers a little tricky ;)
I'm surprised half of your Vodafone visitors have no serial number
but I believe this is user settable. Can anyone confirm this as I
haven't got an off-the-shelf Vodafone mobile handy today?
Although this isn't much help with old mobiles, most Openwave mobiles
these days handle cookies.

Also check your HTTP headers for x-phone-uid or HTTP_X_UP_SUBNO which
are respective Vodafone and Openwave unique IDs. More on Vodafone
headers can be found in http://developers.vodafone.jp/dp/tool_dl/
