Recent Progress of iPhone’s Way to China
Seems iPhone coming to China becomes much closer, from the announced approval by State Wireless Inspection Center of China. See picture below. Source query page is here.

The device is marked as ‘GSM/WCDMA/蓝牙移动电话机’ ,which means ‘GSM/WCDMA/Bluetooth Mobile Phone’, not the famous ‘iPhone’. But is any other phone devices made by Apple?!
PCWorld has a detailed report here. But what I’ve learned is from Sina News(Chinese).
It even says due to the Apple’s nonnegotiable attitude on his business model of revenue sharing with the carrier China Unicom has become not so eager and enthusiastic as used to be.
Besides, to enter the mainland market there’s another barrier: WIFI module. ‘Coz MIT officially doesn’t allow the existence of such a mobile device with WIFI function.
Update(Jul 13,2009): Sina says Apple has agreed that China Unicom will be the one that will sell iphone to the market. As to when and how, just a matter of time. And no wifi for sure.
