This week, Apple launched a web-based tool to check the Activation Lock status of iOS devices such as iPhones, iPads and iPod Touches. Here, users can go to a web site, enter the device’s IMEI number or serial number and see if the Find My iPhone feature has been activated.
The Find My iPhone feature aims to prevent the purchase of stolen or disabled products and can feature an Activation Lock functionality, which prevents activation unless authorized by the user. The Activation Lock was introduced in iOS 7 & is enabled by default in iOS 8.
