This is my second year with at&t service.
Let me tell you besides multiple dropped calls, when it comes to the day-light savings time at&t is a big FAIL!
I remember that I had written similar story last year...
Last year, the clock was not re-set till 2/3PM.
The improvement is that the cell is updated at around 11/12 PM. Well, at&t you better update your tower or system at 2AM.
