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 Sunrise. This is when an Official Factory Apple Unlock Service is required.

An Official Apple Unlock removes ALL network restrictions imposed by Sunrise 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 Sunrise 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 Sunrise 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.

    I never expected this process to be quite so simple but their website stated, I got my unlock within 48hrs and my iPhone 5c is now unlocked and working perfectly with a Vodafone sim. I will definitely recommend. Thanks

    I was referred to this site by my friend so was already confident that this was not one of the many scam sites out there. They did exaclty what they promised and unlocked my phone from Vodafone very quickly. I now too, can confidently recommend this service and its results. Simply don't go anywhere else!

    I took my iPhone 6 to Australia with me and only realised whilst I was there that I couldn't use another sim card in it Orange were less than helpful and would not unlock my phone for me so after searching the internet for a solution I found these guys and without any problems my phone was unlocked in just a couple of days.

    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.

    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

    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.

    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!!
