Dear client
I have read your description and understood your need of developing i phone application that takes the phone number from the mobile device settings, shows it to the user to confirm and then communicates to a server to sign up the device
Server sends an SMS with a 6-digits random code to that mobile number (I will supply server side). On the iPhone app side, following user clicking "Sign up", the application will wait for an SMS to be received, read the 6-digits random code (or let user type it in). It will send that code to the server and show a message to user depending on server's response saying whether signup was successful or not.
