Yes! I spent about an hour and a half on the phone tonight with a very pleasant (and PATIENT!) Nikon rep, updating my D 90 firmware...fool that I was, I figured it would be a quick and easy process. The version I now have is; A. 1.00, B. 1.00 L. 1.006
I originally called to get help setting my D 90 and SB 600 for wireless operation. The poor lady and I tried everything to get it to work, and finally, she discovered somewhere in the fine print, a little statement that the on-board flash head needed to be raised! It worked, and I immemdiately turned it down to 1/128 power, so it wouldn't affect exposure.
