Mashable is reporting that Facebook has temporarily disabled the sharing of address and phone number information with app developers.
According to Facebook's statement, the move was due to "useful feedback" they received over the past few days.

Over the past 24 hours, it has been widely reported that Facebook is sharing more than you might think with app developers. Apparently, when you authorize the app to access your basic info, included in that info are you home address and phone number if you have added that info to your profile.
My simple advice for combating this issue: If you aren't comfortable with app developers knowing where you live or what your phone number is, then don't add the info to your profile or don't use the app. Unless Facebook does something to further limit the info app developers collect, these are the only two ways you can prevent this from happening.
Before everyone freaks out too much, please remember that 10-15 years ago, this information was all public for most people...remember the phone book?
