Have a lot of friends on Facebook? Do you have people added on your contact list that you don’t know, possibly residing in a different continent? If you don’t contact them via the social giant, why would you want them accessible on your phone?
Although Windows Phone 7 performs extremely well with integrating with Facebook, some of us just wish to have a more personal experience with our phone should our social network contact list be rather large. Many potential WP7 users are asking (and have previously asked) about turning the synchronization feature within the People hub in the OS off.
While you can’t completely turn it off without removing the Facebook account, there’s an easy and simple setting within the People configuration section that sets between “Show all my Facebook friends” and “Only add Facebook information to existing contacts”. To achieve the desired alteration, go to the following location:
Settings > Applications > People
If you’d like to have your Facebook friends added automatically again, simply reverse the change. Personally, I began kicking people off my friends list and kept my phone synchronizing everything.
