Get users number from iPhone using HTML5/jQuery

Question

Is there a method for getting the iPhone users phone number using HTML5/jQuery?

All I see is how to do this with the SDK.

EDIT:

So far the only thing

Answer 1

There is a Draft from W3C on Device API. This API will provide access (submitted to user permission) to Tasks, Contacts, Calendar, Camera, Microphone, Messaging Service, Communication Log, System Information (device information, battery level, network status, ...),... But it is not yet implmented in any browser.

Because of a big expectation, these APIs will probably be implemented very quickly in WebKit (base of iPhone and Android browsers). Mozilla is working on a draft implementation of Contact API with the Contact AddOn
