In the "early bird catches the worm, unless its iPhone has caught a bug" department, Apple's beloved gadget reportedly has a glitch that means if users set a one-time alarm to wake them tomorrow, they may well end up sleeping in.

Engadget and other media outlets are reporting that Twitter lit up today with lots of grumpy comments from people who were cheated out of greeting the New Year in their desired fashion because their iPhone alarm clocks failed to ring.

The bug reportedly could ruin your plans for January 2 as well, if you let it. But there's an easy fix, and come the 3rd, the glitch should evaporate. Apple told Engadget:

"We're aware of an issue related to nonrepeating alarms set for January 1 or 2. Customers can set recurring alarms for those dates and all alarms will work properly beginning January 3."

So you need only set a recurring alarm to sidestep the problem and get a good night's rest.

In November the iPhone's alarm was off by an hour, in a mix-up related to Daylight Savings Time. Judging from this latest error, iPhone users weren't the only ones affected then: Apple itself apparently didn't get the, ahem, wake-up call.
