Consume web service with GPRS -- dotnet compact framework

Hi Peter

If have installed .NETCF Service Pack 3 onto my devices but the problem
still exists.
I am testing on smartphone 2003 and ppc 2003

I have found that calling the webservice using http post works for muliple
webrequest, so this can be a fix for me if it comes to that.

Here is some sample test code,

It works fine over gprs if I use my httprequesttest method muliple times, if
I use the my webserviceproxytest it only works once over gprs.
They both work fine if connected through acticesync.

Thanks
Brad

Solution is to use the ip address of the webservice rather than the domain
name.
