Engadget got a copy of AT&T's response to the FCC inquiries, and to sum it up: the Death Star finds the FCC's lack of faith disturbing. The telecom giant says that it neither supported not opposed the Google Voice apps for iPhone -- in fact, Apple didn't mention the GV apps to AT&T, nor does Apple typically consult AT&T on App Store approvals. The Apple & Google responses are just coming in now.
In a section of the letter that Engadget has posted, AT&T does acknowledge rare occasions where the company has consulted on app approvals with Apple -- but only where an app might be responsible for 'significant network congestion,' like SlingPlayer. Are we to assume from this that any telephony-related geldings or rejections (ahem, no Skype over 3G) are due to Apple acting completely on its own? That's a mite far-fetched, but with any luck we'll be seeing a similar letter from Apple shortly.
