I downloaded and installed this upgrade. I received an error at the very end of the upgrade (sorry I didnt capture the error). I had to load the backup that the loader created. I lost my Cingular browser but still had the BB browser. I had Cingular push my service books to get my browser back. I had to delete and re-install BBtoday because the time was set to GMT. I've also noticed that with my BBWeather, when I hit the backlight button to the higher level, BBWeather switches my location.
