If I purchase a new iphone 4 from Apple can it be unlocked? Is there a way to tell before buying if that phone can or cannot be unlocked as I don't want to purchase one and find out it cannot be unlocked and wait for new crack. Is there way to downgrade OS in some way and than do the hack. thx
It won't be able to be downgraded since SHSH blobs won't be saved. Additionally, it's not possible to downgrade the baseband on the 4, so you would be waiting for a new unlock tool.
You'll have to hope to get one on 4.0.2. Like Yeow said, you'll have to take a risk to find out. Ask the reps for the oldest stock they have (preferably one from the back I'd suppose) and hope it's on 4.0.2. Otherwise you'd have to wait a while for the new unlock if it's on 4.1.
One time I went to Rogers and ask for an exchange from 16gb to 32gb, he took one out. I ask him if I could see what firmware is on it. I told him if that is the firmware i wanted, then I will take it, if it is not , then I wouldn't want to exchange. He said fine but just only one time. To my surprise, it was just what i wanted, so I took it and had an exchange.
It also depends on the person , treat him nice like a King, then he will feel good and please you, just a thought
