I live in Arizona. We only do MST here. Despite this, during the recent daylight savings time switchover this weekend, my phone decided to update itself to MDT. This was not fixed until I went off airplane mode. This caused me to end up waking up an hour earlier than when my alarm was supposed to be set.
The automatic timezone should be switched over to be GPS based, instead of being entirely reliant on the cell network (and having the ability to reach it).
