Masimo jailbroke iPhones to try to keep the Apple Watch banned.

That’s according to the US Customs and Border Protection’s (CBP) recently-published January 12th ruling that approved Apple’s modification meant to lift the Apple Watch ban.

CBP chief Dax Terrill wrote that Masimo installed “otherwise restricted software that, but for the jailbreaking, would not have been feasible.” He concluded that the software change “would appear to resolve the issue of infringement.”
