An interesting piece from The Verge suggesting that Google Maps got the boot a year before Apple and Google’s contract was up:

Apple apparently felt that the older Google Maps-powered Maps in iOS were falling behind Android — particularly since they didn’t have access to turn-by-turn navigation, which Google has shipped on Android phones for several years. The Wall Street Journal reported in June that Google also wanted more prominent branding and the ability to add features like Latitude, and executives at the search giant were unhappy with Apple’s renewal terms.

Neither company looks good here.
