Unlocking policies with the various networks differ greatly. If you bought an iPhone 2nd hand or on Ebay for example, were gifted an iPhone, if you are not the original contract holder or if a contract period remains, to name but a few, you probably will not meet the requirements to unlock directly via the network. This is when an Official Factory Apple Unlock Service is required.

An Official Apple Unlock service removes ALL network restrictions imposed by the existing network and allows your iPhone 4 to be used with ANY network, around the World. Unless stated, as long as your iPhone 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 iPhone will be unlocked to use any sim card and no longer limited to any individual provider.

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 the network it is locked to. 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.

How to unlock iPhone 4:
  1. Locate your IMEI number (Detailed help on how to find your imei is available here)
  2. Select the Network/Country that your iPhone 4 is CURRENTLY locked to.
  3. Order your iPhone Unlock - Instant submission upon payment.
  4. Unlock confirmation email sent immediately upon status update.
  5. Simply insert a new Sim card whilst connected to an active WiFi signal to complete the unlock.

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.

    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.

    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

    I needed a little bit of help with my unlock but it was dealt with very promptly, they got back to me straight away and I'm not the happy owner of a fully unlocked iPhone 6. Thanks

    I found cheaper unlocks but not on sites that instilled any confidence in me. I spoke to LiveChat to eliminate any doubts I had and made my order on Monday lunchtime. The service was quoted at 13 working days but I had my unlock confirmation the very next day. Clear and simple instructions to complete the unlock. My phone is an iPhone 4s which WAS locked to O2... not any more!

    The requirement for unlocking your phone doesn't come around that often but I used this service 1 year ago and I was very relieved to find our old communication and use them again. Quicker than the first time and obviously the service has become more refined because great customer service, communication and much simpler to complete. See you again in another 2 years!!

    I purchased an iPhone from a visitor from England but needed it unlocked for Movistar Spain. On just the 2nd day I received the unlock confirmation and it worked 1st time. I was fearful it would not unlock because I was in Spain but I need not have worried. Great service

    After trying 2 other companies on ebay, neither delivering and still chasing refunds, I was close to giving up. Of course the ebay services were a lot cheaper and that should obviously have been the alarm bell!! This service could not be more different, profession, fast and I could actually speak to a real person on live chat. Don't waste your time and money on cheap sites, they don't work. You get what you pay for! Brilliant
