Unlocking policies with the various networks differ greatly. If you bought an iPhone 2nd hand or were gifted an iPhone, if you are not the original contract holder or if a contract period remains (to name but a few) it's likely you will not meet the requirements to unlock directly via AT&T. This is when an Official Factory Apple Unlock Service is required.

An Official Apple Unlock removes ALL network restrictions imposed by AT&T both in and around the world. This allows your iPhone 4 to be used with ANY network and unlocked from anywhere in the world. Unless stated, as long as your iPhone 4 has not been reported 'lost or stolen', any iPhone 4 can be unlocked, regardless of contractual period (unless stated) etc. Once unlocked you are able to swap and change network Sim cards at your will. Your will be unlocked to use any sim card and no longer limited to just AT&T in .

To unlock your iPhone 4 with an Official Permanent iPhone Unlock all we require is the IMEI of the phone and a contact email address to receive all correspondence and ultimately, the 'Unlock Confirmation'.

An IMEI number is a unique 15 digit number that identifies your handset and its lock to the AT&T network. The process updates your IMEI on the Apple GSX database and it is marked as 'Unlocked/Whitelisted/Sim Free'. This is the only permanent unlock, recognised by Apple.

The iPhone 4 was first unveiled on June 7, 2010 at Apple's Worldwide Developers Conference in San Francisco and soon after released in the United States, United Kingdom, France, Germany and Japan on June 24, 2010. It was the 4th generation of iPhone, at the time, succeeding the 3GS and preceding the 4S.

The iPhone 4 was the first of the iPhone range to include a front-facing camera and the first to be released in a version for CDMA networks, ending AT&T's period as the exclusive carrier of iPhone products in the United States.

At the time Apple claimed the iPhone 4 to be the thinnest smartphone in the World. The iPhone 4 also introduced Apple's new high-resolution "Retina Display". The iPhone 4 also introduced iOS 4 which included Facetime and multitasking.

It was succeeded as Apple's flagship smartphone in 2011 by the iPhone 4S. However, iPhone 4 continued to be produced until 2013.

All iPhone 4 models on networks that support Official Apple Factory IMEI unlocking can be unlocked with this service.

    Lets face it, the only reason we read these reviews is to get the confidence of those who have gone before us! It's the only reason I have taken the time to add this, simply because the service and customer service was beyond all of my expectations. I took the chance and I am pleased to say it worked, my iPhone 5s was unlocked from the Vodafone network in under 3 days. Cannot recommend highly enough. Great job

    Wasn't sure I could trust an online site but I was proven wrong. My brother has already unlocked his with them since too.

    I was in a hurry to unlock my phone and was bombarded with confusing websites. I found this site and could see they had lots of satisfied customers. The very next day I received my unlock confirmation and simply inserting a new sim card in to the phone, it was recognised and I have been using it without a problem since. The service was excellent

    Spent about a week being told by local shops and Vodafone that I could not get unlocked, I thought I was stuck with an iPhone that I was never going to get unlocked. Found officialappleunlock this morning and within a few days it was unlocked. Seriously impressed and can highly recommend to others.

    I do highly recommend this service, it's awesome. My only reason for a 4 star reviews was I was quoted 24 hours for unlock and after 24 hours I was worried I had been a victim of a scam. The unlock was completed in under 48hrs however!

    I was tasked with unlocking our 7 company iPhones... All were unlocked from the Orange network within the timescale quoted and contrary to my expectations, the whole process was simple and easy. I had no further involvement other than submitted the IMEI's, they did everything and I simply received an email confirming the unlock for each handset. Will definitely use for all our unlocking requirements.
