Apple on Friday offered a rare glimpse into the exclusive agreement between the iPhone maker and AT&T, when it officially responded to an inquiry from the Federal Communications Commission and explained its role in the absence of Google Voice from the App Store.

Apple filed a series of official answers to queries from the Federal Communications Commission, and provided the answers publicly on its Web site. In the responses, Apple stated that Google Voice was, contrary to media reports, not rejected from the App Store, but remains under review. In addition, it stated that the software has been delayed solely by Apple.

Apple did note that it continues to fulfill the obligations of its contract with AT&T. The contract states that Apple will not allow the iPhone to access voice over IP services via the AT&T cellular network. Apple said it is unsure whether Google Voice includes VOIP elements in how it routes calls. However, the contract with AT&T did not specifically prohibit the Google Voice application from being approved — that issue was entirely with the application’s apparent mimicking of the iPhone’s core features, Apple said.

AT&T also issued a statement Friday denying any involvement in the state of apparent limbo the Google Voice iPhone software currently finds itself in. AT&T and Apple both stated that AT&T was never contacted by Apple for consultation on the Google Voice application, but that the decision was made solely by the iPhone maker. In the AT&T statement, Jim Cicconi, AT&T senior executive vice president, external and legislative affairs, encouraged Google Voice users to access the application from the Web.

“Let me state unequivocally, AT&T had no role in any decision by Apple to not accept the Google Voice application for inclusion in the Apple App Store,” Cicconi said. “AT&T was not asked about the matter by Apple at any time, nor did we offer any view one way or the other.”
