According to the USA Today Apple and AT&T (and Google presumably, although not mentioned by USA Today) are set to release their statements to the Federal Communications Commission to explain why Google's free Google Voice service and associated apps were banned from the iPhone.
The article goes onto mention that Google may find itself in some bother over the company denying the use of the VoIP Skype on the Android phone platform.
Consumers who use Android, the Google-developed operating system for wireless devices, can't use Skype, a leading Voice over Internet Protocol (VoIP) service. A pioneer in free Internet calling, Skype allows you to talk as long as you want without draining cellphone minutes.
Android users get Skype Lite, a watered-down version of the original that routes calls over traditional phone networks -- not the Internet. As a result, long-distance calls are still cheap or free, but cellphone minutes are gobbled up every time a Skype Lite call is made.
Google has reportedly been asked to address its own application approval process for Android as part of the FCC's investigation.
