Is it Possible to Unlock Verizon (CDMA) iPhone 4?

Verizon (CDMA) iPhone 4 has already been jailbroken on iOS 4.2.6 using GreenPois0n tool. What about unlock? Is it possible to unlock Verizon iPhone 4? Can we use Verizon iPhone 4 on Sprint network or on any other CDMA operator? Can Verizon iPhone 4 work on GSM networks as well like AT&T iPhone 4? Well, it’s hard to answer all of these questions. We’ll just discuss the options below.

Can it work on GSM network?
The answer is “No”. Verizon iPhone 4 is powered by Qualcomm MDM6600 chip which supports both GSM and CDMA but Verizon iPhone will only work on CDMA only due to lack of SIM slot. Apple didn’t include SIM/GSM support.

Can it work on any CDMA network in US?

The answer to this question is “Yes” and “No”. Legally you can’t unlock CDMA iPhone 4 as it requires an “ESN/MEID” (Globally unique number identifying a CDMA mobile station equipment) from a donor phone in service and this is considered as a federal crime in US.

Let’s discuss the illegal options:

  1. Even if it’s unlocked, you will still need someone on Sprint network to activate it on their system which I can assure isn’t a piece of cake.
  2. Sprint offers the facility to upgrade to a free smartphone that supports 3G data. What you can do is that you take free phone’s ESN and put it in CDMA iPhone 4 by uncloking or any other means. This way when Sprint will activate that ESN, it won’t know it’s an iPhone 4, it will look like a Sprint smartphone on their side.

Can it work on any CDMA network outside US?

Well if it can work on any US CDMA carrier, it should be able to work on CDMA operators outside US as well. Having said that, it might not be that easy as there must be some adjustments that would be required on per carrier basis.

    after jailbreaking an iphone yer warranty is gone, the way around this is to plug yer IPHONE into ITUNES and do a reset using ITUNES to bring it back to stock for repairs and warranty options..
    NOTE, U WILLL BRICK yer iphone if u choose to erase all data by the method of going through the setttings menu on the actual Iphone it self HTH!

  13. Ashish says:

    I have brought a Verizon CDMA iphone 4 from US & willing to get a ‘Reliance’ CDMA number for it here from India. They initially said it is possible with the help of MEID (Mobile Equipment Identifiers) number but then after one week, they said ‘NO, it needs the RSN number, which usually comes on the box’. I do not have the box now with me. Could anyone help how to get the RSN number from the phone? Please help otherwise I would not be able to use the phone here. Thanks

  14. John says:

    Can a Verizon I4 I phone be used in canada with Rogers, or Telus networks? do not know which system these companies use in Canada?

  15. Jake says:

    Ashish, I looked at the box of my Verizon iphone, and there is nothing like a RSN number on it. There is ESN, MEID and UPC – but no RSN. Not sure what your phone carrier is asking you for. Let us know if you have found a solution. Ebay India is selling CDMA iphones usable n Reliance, so there must be some way to activate them.

  32. MUNCH says:

    1. AN&T and any phone that uses a SIM CARD = GSM.
    2. Sprint, Verizon phones NOT using SIM = CDMA.
    Two very different networks. Hope this helps.

    oops AT&T lol

  54. Stephanie says:

    AT&T iPhone 4 CAN be jailbroken and unlocked to work with another carrier as for the Verizon iPhone I don’t see how because it doesn’t even have a sim card slot as we know verizon doesn’t have sims.As far as sprint iPhone 4 if it was bought before nov 10th it can be unlocked anything after they locked the simcard meaning it can no longer be unlocked.

  55. tatiana says:
