Facebook is now allowing third-
party apps access to your phone number and address, they
mentioned on their developers'blog. They said they will now be
making this information accessible as part of the User Graph project. What this means is third party applications like
'Farmville' and 'Stalker' will now
be able to access your address and phone number. The way
around this, don't use the app.
Or don't put your phone number and address up if you
do use the app.

Facebook says that because this is sensitive information to give out, users agree to give
permission to the apps to access their phone number and
address when they first add the application. However, users are most likely going to miss the
words phone number and address in their scurry to get the applications.
Thankfully, only you have control of your contact information
being shared via Facebook. Your friends' careless sharing actions will not release your contact information out to these app
developers.
We're expecting a big hoo-ha about this but what it comes
down to is simple. Don't put any information up on Facebook you're not even in the slightest
bit comfortable getting around.
If Facebook apps are the only way you entertain yourself (I
mean, come on!), but you don't want the makers of these
applications to have your information (consider that you're also using these applications for free and developers are businessmen too), just don't put sensitive
information up on your profile.
