Wrong. I have Google Voice on my iPhone's desktop. It is in HTML5 form, and it works fine. I inherit my google addess list, I get the transcript of any messages left, a list of phone calls, all in Mobile Safari.
What Apple rejected was an app that apparently hijacked the user interface and substituted its own address book and message list. Could have told them that Steve Jobs doesn't do that. The UI is guarded like the family jewels. Google had to know that, didn't they? Could they have been arrogant? No, never.
Hmm. Google Voice rejected (headlines! outrage!), which makes Gigantic Google the Victim of Sour Apple. Very quickly thereafter, the OS they had bought years earlier is unveiled, ready to run on mobile phones, and, they give it away... FREE!... to any public-spirited hardware manufacturer who will battle against the mighty behemoth who is drowning tiny developers in cash! (That just furthers their evil intention.)
Free is... OPEN! LOVE! FLOWERS! The Google search algorithms? Not free. Your data? Free for them. Expensive for advertisers.
Sooner or later, it's going to dawn on Google that the best strategy for them will be to give away free software and phones to every man and woman on Earth, the better to becoming trillionaires.
Meanwhile, there's no way for the present Apple strategy, to have a tightly-controlled platform that peacefully coexists with every platform on the Internet and is more and more integrated with Windows and Linux, to take over 25-30% of the market, if that.
