Apple Removes Tool to Check if an iPhone or iPad is Activation Locked
Apple has removed its Activation Lock status checker on iCloud.com at some point in the past few days. The tool enabled users to enter the serial number or IMEI of an iPhone, iPad, or iPod touch and find out if the device is secured with Activation Lock, helping buyers avoid purchasing a device locked to another user.
An individual purchasing a used iPhone on eBay or another website, for example, was able to request the device's serial number and use Apple's tool to verify that Activation Lock had been turned off. If the device was still locked, or if the seller refused to provide the serial number, then it was likely lost or stolen.
When you visit icloud.com/activationlock you’ll find Apple’s 404 “Not Found” page, instead of the tool that has become the de facto authentication step for person-to-person iPhone and iPad sales. theverge
