See my post above. In many ways, I regret buying an iphone4. My wife's experience with nexus s has been much more hassle free than mine.
There are definitely things I prefer on iPhone. One case in point is that although I often see crashes on apps, they just shut down quietly and I restart. Android let's my wife know that an app has crashed.
I also upgraded my wife's phone to android 4.1. It took 5-10 mins total. I'm dreading my IOS6 update which I am estimating will take me 8h (inc. reinstall of my purchases via cydia - which I am forced to do if I want the functionality that I WANT vs what apple lets me have).
