I had the same problem with my iPhone 4S. I trusted the time on the phone and set my bedroom clock to the same time only to find out in the morning, Monday, that my wife and I were running late getting to work. I had to take the phone off automatic change and put it on manual to get the correct time. Later in the morning my phone received a software update. Watched it go through the software update and restart after which time I put it back on automatic and behold the phone had the correct time on it after I put it on automatic. It was odd that my wife's phone did not have the same problem as mine. We purchased both phone's at the same time. The only thing that I could deduce from this would be that there was a batch of phones that did not get the updated software package when they we made and now that the software update has been delivered we should not have any additional problems that pertain to daylight savings time!
