BlackBerry App update

I have a BlackBerry app that was developed using the Eclipse development environment. This is a simple app that calculates a person's BMI by accepting their height and weight. I require a few updates to this app. One of which is to send an e-mail to a person using a "Share this application" function. Here is the list of updates, Update all prompts so that Lap-Band is on one line (there are currently 2 prompts of text) Add "share this app" function which allows the use to type in an e-mail address. This application will create and send an e-mail to that address with a link to the app. Change the qualified value for a lap-band. Currently it is set to 35, it needs to be set to 30. I have all of the source code needed to complete the work required.
