China Unicom has announced that they will start carrying the 8GB iPhone 3GS with wifi support, possibly within the week. No other details were given, but rumors pin an August 9 release date with a price tag of 4999 renminbi ($736) with a two-year contract.
In the past, many smartphone providers had to drop wifi support in order to meet with Chinese government guidelines, because all such devices were to use a domestically developed protocol called WAPI (WLAN Authentication and Privacy Infrastructure).
Macworld reports that last month, Chinese regulators issued a license for an iPhone that includes wifi support utilizing the WAPI protocol. As Macworld points out, availability of this device will help bring up official iPhones sales as the only ones that currently offer wifi support are only available in the gray market. However, there is no word on official availability of the iPhone 4.
