Simple iPhone App - Start Now!!!!

The current project is an app that would need the ability to send an anonymous email (perhaps coming from our server) to a friend or family member. The user should be able to choose from a main screen the type of email he/she wishes to send. There would also need to be an archive of messages sent, ability to delete those messages and the ability to password protect the application. App will need to be usable on the iPhone as well as the iPod Touch.
