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:
- 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.
- 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.
