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 T-Mobile. This is when an Official Factory Apple Unlock Service is required.

An Official Apple Unlock removes ALL network restrictions imposed by T-Mobile 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 T-Mobile 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 T-Mobile 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.

How to unlock an iPhone 4 on T-Mobile:
  1. Locate your IMEI number (Detailed help on how to find your imei is available here)
  2. Select iPhone 4 from the model options.
  3. Select the Country your T-Mobile iPhone is locked to.
  4. Confirm the T-Mobile network by selecting it once the country has been selected.
  5. Order your iPhone Unlock - Instant submission upon payment.
  6. Unlock confirmation email sent immediately upon status update.
  7. 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.

    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

    I bought what I thought was an unlocked iPhone but they are not really unlocked!!I bought an unlocked iPhone 6 to take with us on our 6 months travels throughout Europe so that we could use local sim cards during our trip and avoid high roaming charges. I put my UK O2 sim in the phone and it worked fine but when we than came to put a French sim card in the phone it said Sim Not Valid!! After phone calls to Carphone Warehouse I was told that it would only work with the O2 network now! It's not unlocked then is it!!When I came across this service online the customer support girl explained everything clearly to me and the 'Next Tether Policy' whatever that meant? My only option was to unlock my handset and chose to go ahead because the timescale was so quick compared to other sites I'd seen. Took less than 2 days to get my phone unlocked and now I truly have an unlocked phone that will allow me to use any network.CAnnot thank these guys enough HIGHLY RECOMMENDED

    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!

    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

    Was told by local shop that my phone could only be unlocked by Vodafone at an extortionate price and a 4 week wait. Chose www.officialappleunlcock.com web site after looking at many. The process was simple, quick and successful. I will recommend this site to anyone who asks about iPhone unlocking.

    My EE iPhone that is still in contract was unlocked in just 3 days when EE would not even enterain it. Bit expensive but less than I'd found elsewhere and the price was justified when it was explained to me that the handset is heavily subsidised when purchased on a contract.

    I must say, I was really impressed how simple and fast the process was. The services state 'working days' only but I ordered my unlock on Saturday evening and received my unlock on a Sunday which both surprised and pleased me, no end. Thanks for a great jub.
