suraj.sun writes with an update to the news from a few days ago about Apple pulling Google Voice apps for the iPhone. Their actions have raised the interest of the FCC, which is now beginning an investigation into the matter. "In a letter sent to Apple, the FCC asked the company why it turned down Google Voice for the iPhone and pulled several other Google Voice-related programs from the iPhone's only sanctioned online mart. The FCC also sent similar letters to both AT&T — Apple's exclusive carrier partner in the US — and Google, asking both firms to provide more information on the issue. The FCC's letter asked Apple whether it rejected Google Voice and dumped other applications on its own, or 'in consultation with AT&T,' and if the latter, to describe the conversations the partners had. In other questions, the FCC asked Apple whether AT&T has any role in the approval of iPhone applications, wants the company to explain how Google Voice differs from any other VoIP software that has been approved, and requested a list of all applications that have been rejected and why."
