Wow, I'm sorry you haven't received your OTA upgrade as yet. I'm not a pro at this but I'm sure others on here are helpful and more knowledgeable than I am. You can also do a manual install using NaviFirm. As far as variant is concerned I did a little research and found this :

SELECTING A FIRMWARE IMAGE (N9 SPECIFIC)

Main firmware images for the Nokia N9 are divided up into "variants" by regions of the world. Except for carrier-branded variants and the 003 (China) firmware, these images are more or less the same.

001 - Europe (1), Latin/South America, South Africa
003 - China
005 - Asia/Pacific (incl. Australia/New Zealand, excl. China)
006 - Middle East
009 - Europe (2)
2xx, 3xx, 4xx - "Country Variant" and carrier-branded images

In settings---> about product and under version, mine is PR1.3, then a long number under that ending in _PR_009. Not sure if this means mine is a European variant. I'm not sure if it said the same before the upgrade. Anyway, here's where I found this info http://talk.maemo.org/showthread.php?t=82693 Good luck buddy
