We've recently been following the FCC's inquiry into Apple's rejection of the Google Voice app. Apple, Google, and AT&T have all officially responded to the FCC's questions: Apple says they haven't actually rejected the app, they're just continuing to "study it," and that it may "alter the iPhone's distinctive user experience by replacing the iPhone's core mobile telephone functionality and Apple user interface with its own user interface for telephone calls, text messaging, and voicemail." The interesting bits of Google's response seem to have been redacted, but they talk a little about the approval process for the Android platform. AT&T claims it had "no role" in the app's rejection and notes that there are no contractual provisions between the two companies for the consideration of individual apps. Reader ZuchinniOne points out a report in The Consumerist analyzing some of the statements made in these filings, as well as TechCrunch's look into the veracity of their claims.
