Some iPhones with Daylight Savings Glitch?

Mashable reported that some iPhones were seeing a problem causing it to improperly adjust to daylight savings time in the U.S.

Daylight saving time hits tonight/tomorrow morning, which means we all lose an hour of sleep unless you have a Verizon iPhone, in which case youll wake up utterly confused, as phones are currently falling back an hour.

They originally pinpoint the problem to Verizon iPhones, but also report that some AT&T iPhones may be affected too.

We've seen reports (another) from our readers that have seen the problem which also seems to affect alarms going off in the morning.
