The Apple-Google scuffle over Google Voice app for iPhone has taken a new turn with the recently-released unredacted version of Google's letter to the Federal Communications Commission (FCC) revealing that Google claims Apple's rejection of the app stemmed from the supposition that the app "duplicated the core dialer functionality of the iPhone."

Google had urged the FCC to release the unredacted version of its August 21 letter because of Apple's persistent claim that the app had not been rejected. The FCC had initiated an investigation into the matter to ascertain whether Apple had rejected Google Voice at its partner AT&T's request, more so as the app helps users make free phone calls.

However, despite Google's letter being made public on Friday, Apple stuck to its earlier stance, reiterating that, contrary to published reports Google's request for its Voice App for the iPhone was still under consideration.

In a Friday statement, Apple said: "We do not agree with all of the statements made by Google in their FCC letter. Apple has not rejected the Google Voice application and we continue to discuss it with Google."

Nonetheless, apparently Google has a screen shot of the actual rejection notice via the iPhone developers' administration, with the formal rejection. In case that is made public Apple will be in a really tight spot and would not be able to persist with its 'misdirection' tactics!
