Doesn't fix the issue where the calendar goes blank for a few seconds when you start the app. In fact, in list view, it goes totally blank until you hit another view. Of course, who's surprised that Apple introduces a new bug in a basic calendar app?
After just 1 hour of use, my iPhone 3G seems a little bit faster than 4.02; Safari opens faster, Google maps is much faster, Skype (as told) works even if there is a message saying that is not supported.
Contacts opens faster, too. But after the 4.0 -> 4.01 -> 4.02 story I can tell that it's better to wait to give a definitive answer.
I made a call with Skype with wifi and I had the impression the phone was a little bit hotter than expected, I'll try again.
