Iphone Application - Facebook login

Simple application featuring 3 pages. Facebook login/registration, homepage after signing in (can be left blank), last page is a file upload (user enters text or submits a picture from camera roll) Registration: Users will register using their Facebook account. Gives the option to post on users Facebook walls. To complete the registration process, there’s a text field that must be completed. **I need a text file populated which keeps the text field together with the users facebook account when registering. Login: Once registration has been done once. Users can login using their Facebook account. You are then presented with the Home Screen. (This can be blank for the meantime - perhaps a button which open the last page) Last page: A simple text field and button to send data to me (requires capturing the Facebook username of person signed in as well) A button which open the camera roll and you can select and send a picture (requires capturing the Facebook username of person signed in as well when submitted)
