I just bought a red/white N73 a few days ago, and was wondering the same thing. As of today, plemix.com has it in stock for a few dollars more than the red/white. Also, I was checking out the Nokia Europe site for the N73, and they said that it came in silver/plum, and red/white. No mention of mocha/white. I wonder if they discontinued it because it wasn't selling as well?
