Thread: iPhone 4 Unlock question

  1. #1
    Default iPhone 4 Unlock question
    I have an iPhone 4 that requires an unlock using what I think is called SAM Prefs. I used this last year when I updated to ios 6 and it worked and was wondering is it still possible to do the same again if I update to ios 7? I have the sim that I used and I have a folder named "Lockdown" saved with other items in that folder called activation_records, escrow_records, pair_records, data_ark.plist, device_private_key.pem, device_public_key.pem. Is this all I need to do an unlock? Any help appreciated as I don't want to update and find I can't unlock the network as the phone would then be useless to me.

    Since it's an iPhone 4, you can save the current SHSH with iFaith then upgrade to iOS 7 to test. If it doesn't work, you can restore it. It's a bit of work to find out if you can't get the info.

    Also, you may want to check out gsmhosting.com. Hopefully, you can find the answer there.... Good luck
