adding censored headers

Hi,
I have just installed wwwoffle and it works very well. With the 'Censored 
Header' Option it is possible to change an existing header line. I would also 
like to add an additional header line.  I'm not so good in C-Programming but 
I think it is only a small change in the file parse.c . With this it would be 
possible for my notebook to act like a mobile phone if it has the same 
headers as a mobile phone sends f.ex. to get wap pages. Some providers only 
allow mobile phones to get them.  Can anybody help me?
Greetings
  Markus
