引き続きすみません。Pod2g氏のTwitterを見たところ、
Anyone with an iPad Mini Retina Cellular that can’t be jb, try: 1. restore and set a passcode. 2. when evasi0n7 asks to unlock, wait…30 seconds, then unlock (last step). Also, try that without a SIM, and please report if you had success. Thanks.
と書いてあったのですが、やはりiPad Mini Retina Cellularモデルは脱獄できないのでしょうか…
