Before the release of iOS 7, AirDrop is confined to OS X Lion and later. As iOS 7 brings AirDrop to iOS devices, file sharing becomes much easier among iPhone, iPad and iPod touch. Using AirDrop, users can share files (photos, videos, websites, locations, and more) with nearby iOS 7 devices through a Wi-Fi network with any configuration and without the need of mass storage devices.
Before using AirDrop to share files, you should be aware that AirDrop is not compatible with all iOS 7 devices; it can be used only on the following devices:
AirDrop uses Bluetooth to create a peer-to-peer Wi-Fi network between the devices. As long as you've enabled both Wi-Fi and Bluetooth on your device, AirDrop will automatically detect nearby supported devices. The devices only need to be close enough to establish a good Wi-Fi connection, making it possible to share files across several rooms.
AirDrop is enabled by default; however you can turn it off by tapping on the AirDrop option in the all-new Control Center on iOS 7. You also have the option to make yourself discoverable to everyone or only people in your contacts, which we'll talk about later.
With several steps you can transfer files to other iOS device users through AirDrop. If the photos, contacts, notes, etc. you are about to share are missing from iPhone, iPad or iPod touch, you can use iPhone Data Recovery for Mac to get them back and then transfer these files with steps below.
Off: Turns off AirDrop.
Contacts Only: Your iOS device is visible only to your contacts.
Everyone: Your iOS device is visible to all nearby iOS devices that use AirDrop.
You can also share notes in Notes app, URLs in Safari, contact cards in the Contacts app, Passbook passes, app listings on the App Store, media listings in iTunes, and stations in iTunes Radio. Besides AirDrop, iOS 7 has a lot more features you might be interested in, and you can check the post How to Use the New Features in iOS 7 for details.
