Can I send a user-entered phone number to a server on iPhone?
<p>I know that Apple does not permit developers to read the phone number of the device and send that to a server.</p>

<p>However, I can't find anything about whether I can send the phone number of the current device <strong>if the user enters it into the app</strong>.</p>

<p>I would like to let people sign up to my service using only their phone number as an identifier (i.e. no need for an email address) and to send them an SMS with a secret code to authenticate them.</p>

<p>Thanks.</p>
