(CNN) -- More hassles for some iPhone 5 users.
Many spent the past week trying to figure out how to deal with a scary new bug.
Apple has now confirmed there's a bug that's causing the phones to consume major amounts of cell data.
It's happening even when the phones are plugged into a Wi-Fi network.
Apple hasn't commented on how widespread the problem might be.
But it pushed out a software update over the weekend that's supposed to fix it.
So far the bug has been a problem for Verizon users... and possibly AT&T.
Apple has already apologized for its new Maps app.
Turns out the app is full of major geographical errors.
