Nokia 3510 wap problem

Hi,
 
I'm using quite new Kannel cvs version as wap gateway.
With the Nokia 3510, when trying most wap sites, and the "Tone services"
from the menu, I get the error message "File too large to be loaded". No
problems with other phones like Ericsson T39...
wapbox.log looks like this:

13:43:31 [8] WARNING: WSP: Content type <text/html> not supported by

Is the  problem in the phone (seems weird since Nokias own services
doesn't work) ?

Or is it something that can be done in the gateway?
