I guess that I am lucky that my provider (MTS Mobility) in Canada didn't send it out until the 27th, so there were probably a few tweaks in after the AT&T problems.

The only problem I have seen so far is that I get unstable WIFI warning messages for WIFI sites that worked before the upgrade (like at home). If I ignore it I still stay on my connection so I am not sure what the warning is about (other than a bug).
