#Facebook To Stop Sharing Phone Numbers http://snapvoip.blogspot.com/
Due to user feedback and concerns regarding the sharing of data, including phone numbers, Facebook is halting the feature until it has a better grasp of the way to share these data with user approval.
Facebook made it available to Facebook developers to share data including phone numbers over the weekend.
Following is the exact statement by Facebook on it's developer site.
Improvements to Permissions for Address and Mobile Number
On Friday, we expanded the information you are able to share with external websites and applications to include your address and mobile number. With this change, you could, for example, easily share your address and mobile phone with a shopping site to streamline the checkout process, or sign up for up-to-the-minute alerts on special deals directly to your mobile phone.
As with the other information you share through our permissions process, you need to explicitly choose to share this data before any application or website can access it, and you can not share your friends’ address or mobile number with applications. Also, like other data you make available to third party apps and websites, you can always clearly see and control the ways your information is being used in the Application Dashboard.
Over the weekend, we got some useful feedback that we could make people more clearly aware of when they are granting access to this data. We agree, and we are making changes to help ensure you only share this information when you intend to do so. We’ll be working to launch these updates as soon as possible, and will be temporarily disabling this feature until those changes are ready. We look forward to re-enabling this improved feature in the next few weeks.
