Plenty of people did the last OTA update without issues. I did it soon as it showed up on my screen and had zero problems. Then again
I don't check for updates again after applying one and see what happens when I apply it a 2nd time
I'll try the manual update later today after it's released. Not worried about it breaking my phone. Worst case I switch my ESN back to my old phone until I get a replacement. Certainly not the end of the world. Best case I am running Froyo while people sit on the sidelines waiting to see if they should upgrade.
