After digging through iOS code and discovering references to experimental networking protocol Li-Fi, iOS hacker and jailbreaker Chris Fromm has uncovered what he believes is confirmation the headphone jack is set to disappear in the next iPhone, within iOS 9.3 beta 1.1.

Fromm explains to iPhone in Canada he uncovered this yesterday, and the code can be found within the following directory within iOS 9.3 beta 1.1:

Recent rumours have suggested the next-generation iPhone would skip the 3.5mm headphone jack, in efforts to make the phone thinner, waterproof and support wireless charging. The existing Lightning connector would then be an all-in-one connector for charging, syncing and headphones.

While it’s easy to jump the gun, reference to this code does not mean the headphone jack will be gone in the next iPhone. We’ll wait for case makers and shell leaks to see if any visual proof may be available.

As expected, some Apple users are unhappy at the thought of the standard headphone jack disappearing in the next iPhone. An online petition started a while back has already surpassed 288,000 signatures.
