iPhone 4s in China come with the PRC Propoganda Edition of Google Maps. Google, in order to stay in China, has given in to China's demand that Maps show areas of dispute between China and another country to be part of China. However, a part of India that clearly belongs to India shows up as part of China.
The state of Arunachal Pradesh shows up on Google Maps in China as part of China. Seeing the Map with the same phone, when taken to a different part of the world, the state belongs to India as it normally would.
