(keitai-l) Keitai User ID/Browser Info

This is a follow-up on a thread from a few weeks ago that was
talking about redirects.  I am trying to find out what sort of
information is stored on a website's log when someone using
a keitai views the site.

i-Mode:
For unofficial sites, no user ID is given.  Instead, the i-mode
gateway address is recorded (i.e. official sites can access
the user ID).  However, information about the phone is recorded 
by unofficial sites. (e.g. DoCoMo/1.0/D502i/c10)

EZaccess/web
Basic WAP problem: user's phone number is recorded in the
log files as the ID.  In the previous thread, I don't remember
seeing any log info on EZaccess/web's browser type, etc.

J-Phone:
Does anyone know what if an ID (if any) is logged?  This is what
was posted as an example from the last thread regarding the type
of cellphone:

http_x_jphone_color: G4
     x_jphone_display: 120*126
     x_jphone_msname: J-DN02
     x_jphone_sound: 4

Thanks,
Jon
