You might not be aware of this but the official Chinese iPhone offered by China Unicom
since October 2009 doesn't include WiFi
-- part of the reason for a continued Chinese grey market for iPhones sourced from neighboring countries. Now we're seeing a China-approved 3G / GSM / Bluetooth device from Apple capable of using China's homegrown WAPI (WLAN Authentication and Privacy Infrastructure) protocol. The new device --
presumably a 4th generation iPhone
-- will join Dell's Mini 3i
as one of a few foreign handsets to feature the Chinese national standard for WLAN. See the 26 April approved regulatory filing after the break.
: The reference to "A1303" in the chinese language filing means this is likely a WAPI version of the iPhone 3GS, not a 4th gen device.
