Beijing time on the morning of January 29th, according to foreign media reports today, Apple opened the VoIP function in the 3G network to iPhone users.
Some VoIP providers said this week that Apple has allowed VoIP software to run on the iPhone. Apple confirmed this on Tuesday, saying it applies to iPhone and newly released iPad tablet PC applications, some of which will be compatible with 3G.
Previously, the iPhone already supported VoIP software, but it was only possible to make calls through Wi-Fi Internet access, but not in 3G networks. Apple had previously banned Google's VoIP software from its iPhone platform, prompting an inquiry from the Federal Communications Commission, which is investigating competition over wireless networks.
Apple's response to this is that because Google Voice, Google's Internet telephony software, has copied some of the iPhone's functions, Apple has restricted its access to the iPhone platform and is conducting research on it.
Two months later, AT&T, the exclusive U.S. carrier for the iPhone, said it had improved technology to allow VoIP services on the iPhone to run over 3G wireless networks, even if it threatened AT&T's core phone business.
AT&T also said that without AT&T's consent, Apple will not allow any VoIP application to run on AT&T's 3G network.
Apple has promised to provide VoIP applications in the software store. FCC Director Julius Genachowski on Thursday applauded Apple's latest decision, saying it "will create more opportunities not only for entrepreneurs, but also for users. ".
