My iPhones airdrop was accidentally on for 1 day on all, can my contacts see my photos?
They can't see anything if you just enable it, you have to physically share a picture by going onto the picture, tap the share icon and a list of available Airdrop contacts will show which you select and confirm before they get the option of accepting/declining it.
How do you use AirDrop to share music from iTunes?
Actually you don't need to use airdrop. Just share your library through WIFI. Go to Itunes menu bar and then "advanced" and turn on home sharing. He will be able to pick and choose whatever songs or apps he likes and take them from your library.
On my iPhone 5, how do I send a picture via Bluetooth?
