Hello, i bought an iPhone 4, with iOS 7.0.4 from Japan, which is locked to SOFTBANK simcard. I've got the card, so i managed to activate the phone, but i cannot use other network. Are there any chances for me to see a way to unlock the phone? I've seen some companies able to do that, but it costs a lot, about 200$ just to unlock the phone. I also wrote an e-mail to SOFTBANK asking if they can unlock the phone since the contract is finished already. Still waiting for the response though. So, are there any hackers still working on Unlocking iPhones with the number four, or they already quited the job and i have no reason to wait and try to jailbreak it?
