Apple I phone Users Are Having a Blue Screen Problem.

The infamous "blue screen of death" seems to have expanded from Windows PCs to iPhones.

Several iPhone 5S owners report that their phones are turning a mean shade of blue and then restarting. Users chiming in on the Apple Support Communities and MacRumors forums said the problem occurs when they use the Numbers app in Apple's iWork suite, which comes free with the new iPhones. But a couple of people report that it also happens when using the ESPN ScoreCenter app.

The bug apparently has been present since the phone launched. One of the forum messages is dated September 21, the day after the 5S went on sale. One possible remedy, at least for users running into BSODs with iWork, is to disable iCloud syncing for the iWork suite, according to The Verge.
