IMEI Based Remote Unlocking for iPhone 4 Restricted to Certain Carriers

Remember the IMEI based remote unlocking service that many websites, specially CutYourSim was practicing few weeks ago? Apparently even the one’s performing the unlock did not know how it all really happened and hence have limited to only few carriers now. From the looks of it, I wouldn’t expect it to return to all carriers either, because this whole process was based on utilizing direct unlock codes from the Apple servers and worked as a permanent unlock. Many users opted for this service and are now enjoying their unlocked iPhone 4’s, but at what cost, now that even the company who used to perform this service have completely stopped doing it.

This is what the company stated;

The unlock will work with any iPhone version, and any baseband version, no need to worry about updating to the latest version anymore. The solution we offer is a permanent solution.   Jailbreaking, or unauthorized hacks are NOT required.  This unlock will carry on forever, you can now update your phone to the newest version without worrying about waiting for an unauthorized unlock to be released. The unlock will work with any iPhone version, and any baseband version, no need to worry pany.about updating to the latest version anymore, your phone will be unlocked forever!

Even though the unlock was being charged $170, many users stuck on currently locked basebands 2.10.1, 3.10.1 and 4.10.1 running on iOS 4.2.1 and above have used this and attained unlock. There were about 400 successful unlocks done, until CutYourSim decided to pull the plug off this service and cancel all pending orders. They claim that they have already refunded the complete amount to users whose iPhones weren’t unlocked. Recently, they again decided to get the service back up, but this time limiting to only certain carriers and not all. Below is the list of carriers that they claim can be unlocked:


  • Optus
  • Telstra
  • Virgin
  • Vodafone


  • Vivo


  • 3 Hutchinson
  • Telenor
  • Telia Hutchinson


  • Orange
  • Ireland
  • O2
  • Vodafone


  • Cellcom
  • Orange
  • Pelephone


  • T-Mobile


  • Netcom
  • Telenor


  • Movistar


  • Hallebop
  • Telia

United Kingdom

  • O2
  • Orange
  • T-Mobile
  • Tesco
  • Vodafone

We have no idea as to how long this service will remain active, as most of the iPhones aren’t carrier locked, but rather just locked. So we will have to wait and watch if they will bring the previous unlock service back so that anyone can unlock their iPhones. If you own an iPhone locked to one of the above carriers then place an unlock order by providing your IMEI over here.

Do you think the $170 price tag is worthy of this unlock or would you rather wait for the iPhone Dev team to come up with the software unlock.
