Delete data
I found out that there's a "delete data after 10 wrong passwords" in setting and I wanna ask which datas it will delete.
iPhone 5s, iOS 8.1.2, non-jailbroken
Copied from page 44 of the user guide iOS8
Erase data after ten failed passcode attempts. Go to Settings > Touch ID & Passcode (iPhone models with Touch ID) or Settings > Passcode (other models), then tap Erase Data. After ten failed passcode attempts, all settings are reset, and all your information and media are erased by removing the encryption key to the data.
