Apple releases iCloud tool to check device Activation Lock status:
Adding to its collection of Web-based security tools, Apple on Wednesday published a webpage that allows users to check a device’s Activation Lock status, ensuring safe and smooth transfer of ownership for used iPhone, iPad and iPod touch models.
Introduced as part of iOS 7, Activation Lock prevents theft and protects lost iOS devices by locking out users who do not know the Apple ID and password registered to that specific device. When activated, the feature prevents nefarious users from disabling Find My iPhone, performing a data wipe or reactivating the device under a different name.
Service from Apple, no more available.
