Too many users are complaining about not being able to activate iDevices after update , and being asked for an Apple ID Activation , here is a little guide about this problem and its resolution :
How does Activation Lock work?
When you enable Find My iPhone on your iPhone, iPad, or iPod touch running iOS 7, your Apple ID 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.
So if you’re stuck on this screen below,
Order “Find My iPhone Activation Lock: Removing Device from Previous Owner/s”
This will remove the Lock so you just have to try the activation again and it will activate normally
Supported Devices: iPhone 4/4S/5/5s/5c
Time: 3-16 business days
THIS SERVICE IS CURRENTLY AVAILABLE FOR AT&T iPHONES ONLY
P.S. No Refunds for WRONG IMEI
Also, Any Charge Back Will Lose Activation and Phone will be Block Forever with no Solution.
