In iOS 9, Apple is adding a feature to help make it easier for Android users to make the switch to an iPhone. Users will be able to download the Move to iOS app from the Google Play Store and wirelessly transfer their data from their old Android to their new iPhone.
Contacts, messages, photos, videos, mail, calendars , wallpapers and DRM-free music and books can also be transferred. The app even compares your current Android apps to iPhone apps. The free apps are automatically downloaded, while the paid apps are added to your wish list in iTunes.
