Fresh install on iPhone and iPad and dropbox sync is still not working after the initial population. I am not seeing any of my attachments with this build that I could see with b34-36.
The beta stripes are also gone from the app icon.
I agree with another poster that the default time to clear the keyboard should not be never.
I really like the improvements to managing the browser tabs on the iPhone and the loading animation in the address bar. The unlock animation is really nice but the quick unlock animation is a bit broken, Also I would suggest making the user confirm the quick unlock code in case they make a mistake.
