I may be barking up totally the wrong tree here, so do please correct me if I'm wrong -
If you have a new iPhone that has been completely wiped (erase all contents and settings), then you perform a jailbreak on the device - is it possible you will then be able to recover data that was on the device before it was wiped?
Hello,
As the others pointed out, it is important to clarify what is meant by "factory reset". On the iPhone for example (models later than 3G), a factory reset will just erase the encryption keys used to encrypt data at rest and generate new ones, making the old data garbage and unreadable.

It seems that you will only get some garbage data on recent iphone. So you will not be able to recover anything without the old encryption keys
Is there any way to recover the old encryption keys? For example with the lockdown file? Or if you have the itunes account connected to it?
