PSA: Sharing iPhone 4S contacts also shares Siri relationships
Just a heads up -- if you send a contact via your iPhone 4S' built in sharing feature, you also share everything in that contact, including relationships set up by [http://www.imore.com/siri). For many this may not be a big deal, but if you value your privacy or you don't particularly want or need a business partner, for example, knowing who your mom is or that playful nickname you have for your girlfriend, you might want to think twice before sharing an entire contact card in the future.
Perhaps Apple could constrain card sharing to common fields in a future iOS update. The odds of me actually wanting to share every detail in a card with someone is virtually nil, especially compared to the odds of me just wanting to share the basic details like email, phone, and address.
