I had no problems with 3.01. I manually updated to 3.02 - still no problems.
I don't know if 3.02 is going to be pushed out over the air - the page on the website just had the directions on how to manually update, but didn't contain the usual paragraphs stating that it would be pushed out gradually for automatic updating via 3G or Wifi. So I would guess you have to manually update to get this one.
