Can't deploy .net app

[John]

Hi

I am using this smartphone device;
http://www.microsoft.com/windowsmobi...phone;emea;191. I
am having problem deploying smartphone app from vs 2005. The error I get is
that this version of activesync is not supported. I have downloaded and
installed version 3.8 but still get the same error. I was not able to deploy
using vs 2003 as well. The device works well otherwise and syncs fine with
outlook via activesync. I am using Norton Internet Security 2004, in case
that has any effect.

How can I deploy my smartphone app to the SDA device?

Thanks

Regards
