Blackberry Test App

I need a Blackberry test-app which consumes existing .net webservice. I have a complete example including source for Android and need to replicate the same for Blackberry OS 6 or higher.

Basically one page with form fields (name, email, address and a few others) which are posted to a .net service, then analyze the result and display it as an inline browser frame. The inline browser frame points to a url which is populated from the response of the .net webservice.

Important Note: the soap request needs to be signed using X509 certificate and the soap response signature needs to be verified, so the developer needs to understand (or have used libraries) to do this or can quickly figure out how to do this (Android sample available using ksoap2 google library)

Please indicate which libraries or methods you inted to use to sign the .net soap request and verify the soap response signatures (if possible provide example of similar solutions on Blackberry)
