Simple WAP from Nokia 6310i

I'm trying to pick up a simple text file from my web server using my
Nokia 6310i. The phone is reporting "file format unknown". The MIME
type is text/plain which the phone lists as acceptable in its HTTP
request. Any ideas what's wrong? Here's the request and response as
captured in a trace at the web server (I've wrapped the accept: line
here). It appears to have worked OK from the web server's viewpoint...

GET /x HTTP/1.1

How are you trying to do that? With the phone's WAP browser?

I played around with this stuff a couple of years ago (and so have
forgotten most of what I discovered) but I think the problem is that the
6310i may indeed be able to receive a text/plain message but the inbuilt
WAP browser doesn't know how to display it -- I believe it can only display
WML pages.

The server trace you gave looks like a successful HTTP exchange, so I think
that part is working.

I did manage to get a Java MIDlet to download and display a text/plain
message on the 6310i, but I think the JVM handles communications
differently from the WAP browser, so that may not be relevant.

Cheers,
Daniel.

Yes.

Yep, that was it.
I encoded it as text/vnd.wap.wml and now it works fine.
