A strange iOS glitch has some iPhone and iPad users complaining after they received undeletable emails dated January 1, 1970.

The emails in question are blank, with no subject or content — which means that sadly we’re not in line for scalper messages about tickets to the farewell concert of Diana Ross and The Supremes (which took place that month), or reminders about meetings we’re very, very late to.

Apple has acknowledged the existence of a somewhat bizarre bug which bricks any iOS devices that has its date set back to 1970 — and confirms that a fix is on the way.

“An upcoming software update will prevent this issue from affecting iOS devices,” Apple notes on one of its support pages.

While there’s no word on exactly when this software update will be made available, it’s good to know that Apple is on the case.
