Simple Java Application for Blackberry

I need a simple Java application for blackberry phones. It should creatively use features specific to Blackberry and connect to the internet via Blackberry service. The actual functionality is very simple: a couple of forms that call a webservice when submitted. ? The webservice is already taken care of. ## Deliverables All source code must be fully commented and easy to follow. I expect a brief architectural design document. I am a developer and I know documentation can be difficult for devs so it can be high level and brief. Design must also be strictly object oriented and should be consistent with what is presented in the design or requirements document.
