I notice one thing that 1.1.1 broke, and it really sucks. When you are in Safari and there is a link to Google Maps, in the old firmware it would hand it off to the Google Maps application, which was really slick and you could then bookmark the address or get directions etc. Now it just displays in Safari which is way less useful. I noticed this on yelp.com listings, which is a pretty useful site to use with the iPhone. Hope this is fixed soon as this is major functionality broken IMO.
For an example, under the map on this page click 'view a larger map/directions'.
