Does the section HTTP-ACCEPT of the http-header change after you installed an external player on for example a Nokia 7650?
For example, I install RealOne player on a 7650. After that the phone supports more mime-types than it already did. Can this be seen in the http-header?
I ask you this because I want to be able to distinct serverside between phones that do have a realone player installed and phones that don't.
