Google's uncensored letter to the FCC regarding the Google Voice app rejection

This directly contradicts what Apple says in their letter, in which they very flatly state that the app is not rejected.
In addition, Apple seems to question certain functions of the GV app, saying they're not sure how it works and are concerned about various aspects of the app. This is pure speculation on my part, but if the two companies were communicating at such a high level then it seems rather far-fetched that a) Apple would not reveal those concerns to Google and b) that Google would not respond and, if necessary, modify the application to address those concerns.
It's certainly interesting.
