Just did the update OTA. No problems at all, went perfectly just like the 1st one. It's early but so far I've found none of the bugs others here are reporting like messed-up wifi, calendar, etc. All my settings and custom configuration are intact. But my N900 has been rock-solid through heavy use since I got it and I've been very careful and conservative about what apps I install so I didn't expect any trouble.

Not a blockbuster update but I didn't expect it to be. Some nice improvements to the browser, other subtle stuff. Overall, good job Nokia!
