Contrary to what others experience with improved battery life after flashing 2.3.3, my battery life has gotten noticeably worse compared to 2.1.1. I was able to get around 40 hours on 2.1.1 (from fully charged to red indicator). After flashing 2.3.3 yesterday and fully charging the phone, it has been less than 20 hours and my battery indicator is down to yellow, which means it will turn red in a couple of hours. All under the same amount of use, same location (i.e. proximity to towers), etc..
I too am having worse battery life... I've also noticed it takes a lot longer to charge up my phone...
i flashed it twice and it just had so many bugs for me. i like the 270 degreee thing and friendstream but i reverted back to 2.1.2. and it was a breath of fresh air. everytime i tried to use the friendstream widget, sense would crash and restart and the scrolling in people was painfully slow which is weird becuase i did not have any of these problems when i first flashed it and as the days went on it got worse and it the typing was unbearably laggy. its a shame cuz i did like it to a point
