Is this possible?

[we found safety]

When a user browses a website from their cell phone (iphone, blackberry etc.), is it possible for the website to read their cell phone number?

From the AT&T Wireless Service Agreement:

This was from the section on data. there would be no occasions when a voice call would connect to an Internet site. All websites track the IP addresses of visitors. The phone number is embedded in the IP address since all phones connect from the same host. Without that there could be no two-way communications. Webpages could not be refreshed.

The only way to see what a website sees is to connect to a website controlled by you to see what information is provided by your phone when connected. They may not display the information to others just as your IP address on a computer may not be visible to others connected to that website.

I don't think so. There is header information that's passed to a website, but that doesn't contain your phone number. Just your ip address and that is usually ATT's IP address.

No, there are not able to see you phone #
