I too can confirm that I received the too man cards message during the time change. I was actually in the middle of texting when my phone completely locked up and would not accept any input for about 2-3 minutes. It finally started moving (very slow) but still would not allow me to turn the device off with the power button. After 10 minutes or so I pulled the battery and it restarted just fine. This is the first time I've seen this and I've been using the Pre since launch. I get the feeling that this had to be related to the time change.
