Unlock Verizon iPhone 4: Is it Possible?

Lots of people are asking us – “Is there any tool available to unlock Verizon iPhone 4“? Although, we can unlock iPhone 4 on AT&T using Ultrasn0w, but can it be used on Verizon network to unlock CDMA iPhone on baseband 01.51.00?

Interestingly, iPhone 4 on Verizon is riding on Qualcomm MDM6600 chip. This is the same chipset as the Droid Pro world phone and supports both GSM and CDMA, which means that Apple *could* have supported GSM! So can it be used to work on AT&T? No! The Verizon phone cannot be used on a GSM network, as it lacks a SIM card. The Verizon phone will only work on CDMA systems not only due to the lack of a SIM but also because of the antennas: as iFixit notes, “this phone supports two cellular frequency bands, while Apple supports five bands in the GSM version.”

According to iOS hacker pyte, unlocking CDMA iPhone 4 would require an ESN/MEID from a donor phone w/ service which is a US federal crime. Even Musclenerd, confirmed that unlocking a VZW iPhone requires adjustment in CDMA settings per-carrier.

And, if unlocked, it will only work with Sprint network and you’d have to approach Sprint to activate your unlocked iPhone 4, which doesn’t seem to be plausible. So you cannot unlock CDMA iPhone 4 at all, neither any tool is available, as of now.

Chose wisely! Unlocking iPhone 4 is very much required, when you are moving out of US and you want to use your iPhone in other countries as well. If you frequently move to other countries or going permanently out of USA, buy AT&T iPhone 4 “ONLY”.

Currently, you can only jailbreak your iPhone 4 on Verizon network using Chronic Dev Team’s flagship Greenpois0n tool. The guide to jailbreak VZW iPhone 4 is same. Just download Greenpois0n tool and follow the guides below.
