Facebook user be aware
According to Facebook new blog post any facebook application now can prompt to user to get his mobile phone number and personal address.
This is very good if the application really needs it but as a facebook user you shouldn’t allow to provide this sensitive information, until you trust the application much. There are many spamming application those collect data from user and may sell those data to third party.
So when you allow an application, check the permission list and think the application really needs it or not. Otherwise you may get in trouble.
For developers who want this information for their application, just use 2 new permissions.
Please remember, most of the facebook applications really don’t need user’s mobile phone number and address.
