Today's the day -- the iPhone officially launches in China on China Unicom. We say officially because it's been available unofficially, in gray market form, since the original iPhone 2G was launched, and with winks and nudges via Apple's unlocked sales in Taiwan and Hong Kong.

So will international sales tumble as the world's biggest market can buy it at home? Will Chinese sales lag in favor of sticking with the unofficial versions from overseas or future Chinese versions that, you know, include Wi-Fi? Or will iPhone numbers just continue to grow, grow, grow?

Either way, welcome China, to the iPhone world!
