Apple iOS 8 devices keep more of users mobile data private, such as location, past Wi-Fi connections, and the all-important MAC address. Marketing firms that gather those MAC addresses wont be able to track your movements (such as where you shop) and serve you ads based on your profile, location and preferences. For Android users, theres no similar protection for MAC addresses, but Apple should not try to keep it for itself. The change in iOS 8 will obscure your identity when your device scans for wireless networks, but it’s not perfect privacy protection.”]
