Apple has introduced a new security feature in iOS 7 called Activation lock, it makes it difficult for anyone to use or
sell your iPhone, iPad, or iPod Touch and stops anyone reactivting your device without your permission.
When you enable Find My iPhone on your iPhone, iPad, or iPod touch running iOS 7, the Apple ID and password you use for iCloud is securely stored on Apple’s activation servers and linked to your device. From that point on, your password will be required before anyone can turn off Find My iPhone on your device, erase your device, or reactivate and use your device.
Activation Lock is enabled automatically when you turn on Find My iPhone in iOS 7, or when you upgrade to iOS 7 from a previous version of iOS that has Find My iPhone already turned on.
Before you sell iPhone that has iOS 7 make sure you Go into Settings > iCloud and turn off the Find My Phone feature. It’s also advisable to “wipe” the device before giving it to someone else.
To do this turn off Find My iPhone, and remove the device from your iCloud account.
On your iOS device, go to Settings > General > Reset > Erase All Content and Settings.
The first step is always to make sure that the phone is unlocked, and background check on the phone. We sell these iphone background checks at http://unlockmyiphone.com.au/unlock/iphone-network-check-service/ you will need the IMEI number of the phone.
