My first problem is: I am having an issue when using a web service. The web
service is written by another department and say its running fine but when I
call it, I sometimes I get a system.net.webexception return instead of the
correct return. Would anyone have any advice or suggest any extra debugging I
could do to find out where this problem might occur?

The second problem I am having is: I also called some functions within the
web service over GPRS and sometimes the function just hangs. The only way I
have found to get the function call to work again is to disconnect the GPRS
connection and reconnect it. However other functions and other programs are
still using the GPRS connection quite happily. Would anyone have experienced
this issue or know where I could look to help solving it?
