my information may be a bit old, but this can be done in a number of ways.
As I understand it
Docomo - in addition to official sites having access to a unique user
number (all phones), newer phones (503i and later, FOMA) having the send
userid permission enabled will also send a user number to any site when
the "utn" attribute is included in the link or form tag.
Vodafone - sends the phone serial number in the HTTP_USER_AGENT header
Au - sends the subscriber id in the HTTP_X_UP_SUBNO header
and one of these could be used id in lieu of cookie for userlogin.
