There is a lot of information about this topic.

One blog entry that you might want to read is here
(http://blogs.msdn.com/jehance/archive/2004/07/12.aspx).

And if you still have questions then you might want to look through the
other posts on this subject.
http://groups-beta.google.com/groups?as_q=device+id&num=10&as_ugroup=microsoft.public.dotnet.framework.compactframework
http://groups-beta.google.com/groups?as_q=device+id&num=10&as_ugroup=microsoft.public.pocketpc.developer

And if you come across any C# code that you need help interpreting, then you
might want to look up a C# to VB.Net converter to find some useful tools out
on the web.
