In a sense, the IPhone pretty much belongs more to Google more than Apple.
Yes, we all know that Apple still has restrictions on their phone that prevent Google from having default apps but you gotta admit, they have quite a good record of apps on the app store. I think Google is trying to turn the IPhone into one of their own Android phone in a sense. In many ways with all these apps Google has been sending. IPhone is actually becoming one of the better Android phones you can get nowadays. Especially considering that more than half of all current Android phones still haven't updated enough to use Google Now.
