Google Voice may finally be available for the iPhone, but the experience will never be the same as it is on Android. Other iPhone apps always direct you to the default dialer and visual voicemail apps, so even if you want to use Google Voice full time, you have to manually navigate it to yourself. On Android, apps like Google Voice integrate directly with the operating system—if you want to make calls with Google Voice, every call you make from the phone's dialer goes through Google Voice. When you click on a phone number in your browser or in Google Maps, it goes through Google Voice instead of sending you to the wrong dialer. True app integration like this makes using custom phone, SMS, voicemail, and even browser apps absolutely seamless on Android, which is something you won't find on the more locked-down iPhone platform.
