application for blackberry

We have an android application that needs to be replicated for blackberry OS (and iPhone there is another project). 1) The user signs in to the app (Login service on the server). 2) If the user credentials are ok, the app gets all needed configurations from another service. The app consists of very simple screens: Login: Has three components (Username, Password, remember me checkbox and sign in button) Configuration screen: Has tree options (Test mode checkbox, change password, change user phone number) Change password screen: Has 4 components, current password, new password, repeat password and save button. Change user phone screen: Has 3 components, Home phone, cellphone, save button.
