O2 unlocking Iphone 5 and I don't have original Itunes account details
Hi
I've bought a IPhone and I've paid the carrier to unlock the iPhone and they have informed that I need the original ITunes account associated with the Phone.
I've been in touch with the previous owner who is a business and says he can't help. Is this a case that I need the original account or can I use my own ?.
Please help !!!
iPhone 5, iOS 8.1.2
