Oh no, they took $2.5 million out of Apple’s $100s of billions what will Apple ever do?

They were convicted of mail fraud and attempted conspiracy of mail fraud.

If they had used FedEX or UPS this wouldn't apply or would it? What they did was fraud but that may not be as severe as mail fraud.

Headline seems to be misleading: it sounds like they were returning real iPhones with doctored serial numbers.
