It's been a while I've been on Android, but I'm looking at coming back to iPhone. However one of my biggest issues was the integration with Google voice. I know in the past Apple was banning Google Voice apps because they didn't want collusion in the walled garden. However my Google Voice number is very important to me, can you easily send and receive calls with Google Voice? Or does it still require a series of third party apps, cumbersome additional screens and settings for each phone call?
