Q&A for How to Carrier Unlock an iPhone

Try using iTunes Recovery. Boot into recovery mode using these steps: Make sure you have iTunes enabled. Plug your phone into iTunes, and hold the home button. When the Apple logo appears, keep on holding until "connect to iTunes" comes up. Then, restore using the restore function.

No, it just means that the iPhone has not been used. Most iPhones come with a stock mobile network, although a few do come unlocked (and are usually more expensive and not with a contract/plan). Note that whether or not an iPhone is locked is region/country dependent.

No.

If you want a password, then go to Settings and add one for the phone. However, there isn't a way to add one to an app yet, not unless the app comes with a password facility.

Voice over can be taken over by pressing home button three times. For screen lock, you will have to connect your iPhone to iTunes and restore it.

Take your iPhone to the Apple store with your receipt and the box.

When you go to switch your service provider, you can put another sim card in from a different SP and it will not show that it is locked.

If you forgot your code, you can only unlock your phone by erasing all data on it. (Unless it becomes a piece of evidence in a terrorism related case and then the FBI will unlock it.)

If you are changing networks (phone service providers) the PUK code allows your existing phone number to be assigned to your new network. In other words, you keep your old number and do not have to tell all your family and friends to update their contacts. On the other hand, you may want a new number!

No you will have to ask AMD to unlock your iPhone before you insert your new GSM SIM.

You might want to unlock it after so it can't save some of your data and settings.

Hold down the power button until it turns off. It should do something called a hard reset, then it should be unfrozen.

Just factory reset it and then log in with your Apple ID. Your employer may need to put in their password to log out of their account first. If you're changing carriers, have them call the carrier to unlock it to all networks, if it's the same network, you should be good to go.

If you found an iPhone, you need to turn it in to the police.

Contact Apple support.

No. More than likely, the IMEI has been blacklisted, and if it's not able to serve as a media device, it's basically a paperweight unless you're capable of "parting it out" to salvage any money you can from it.

Try reformatting it in iTunes, or get another SIM card from an AT&T phone and bypass the setup that way.

Go into settings and change the Apple ID. The main two are under the "iCloud" and the "iTunes and App Store" sections. You may require the current user password. Or just factory reset, and in that case you will definitely need the current user's password.

The phone is either blacklisted or set up for a different carrier. It's impossible to say which one without more information.

If Cspire is a carrier, you can contact them to unlock it if no balance is owed against the device. If not, then find a third party company to unlock it.

Your first option should be to call the carrier that it is locked to. They may refuse if the phone is not paid off or you haven't reached the minimum requirements. If they refuse, or they are too expensive, then look for websites offering this service, such as cell unlocker or unlockmysim.
