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.

How To Unlock iPhone 4 or 3G/3GS with Ultrasn0w [iOS 4.0/4.0.1]

The Jailbreak for iPhone 4 and all other iPhones running iOS 4 has already been released online at Jailbreakme.com by Comex in a way few had expected. Now following that here’s the unlock solution for you all. Use your iPhone 3G/ 3GS/ 4 with any carrier worldwide with this unlock.

This guide has actually been tested on the said devices and works like a charm. The unlock via Ultrasn0w will work on your iPhone 3G, iPhone 3GS and iPhone 4 with almost any baseband. However do make sure that your baseband is one of the following:

Go to Settings > General > About > Modem Firmware to get this info.

iPhone 3G / 3GS Basebands:

  • 04.26.08
  • 05.11.07
  • 05.12.01
  • 05.13.04

iPhone 4 Baseband:

  • 01.59.00

If your baseband is present in the lists above, that’s positive sign. Proceed with the instructions here and you will have an iPhone ready for any network. Jailbreak your iPhone if you haven’t done that already.


Steps to follow:

  • Launch Cydia
  • Click on Manage tab
  • Click on Sources. Click on the Repo that reads “repo666.ultrasn0w.com”. If its not present click on Edit and then Add. Type the URL without quotes.
  • Click on Ultrasn0w and then on the Install button.
  • Finally, Click on Confirm




Make sure you have a working wifi or data connection before you click on Confirm as Cydia will try to download the app. Once the process is over the Reboot Device button will appear. Click on it and wait for your iDevice to restart. And you’re done. While it restarts you may put in any other sim card other than the carrier the phone was locked to. It worked the first time for me and without any issues. The network search is pretty fast and takes around 15 seconds maximum to register network.


Go ahead and unlock your iPhone. Let us know if you run into any issues. We might be able to lend a helping hand as always.
