Two students allegedly tricked Apple into replacing more than 1,000 fake iPhones with real ones, then sold them, Cnet reported. 

Yangyang Zhou and Quan Jiang, who studied engineering in Portland, Oregon, assigned 3069 fake phones to Apple services from April 2017 to March 2018. The devices were sent to them from relatives and friends from China to different addresses.

Students gave gadgets for repair under fictitious names, and also asked friends to do it.

Those documents note that 1,493 of the 3,069 warranty claims netted a replacement iPhone, and Apple estimated that it lost $895,800 as a result.

Zhou, who went to Oregon State University, allegedly shipped the fakes into the US and sent out the replacements they got.
