Are you interested in the ability to unlock iphone 4 4.2 on your awesome iPhone device? Our step by step tutorial will guide you through the process to make it as easy as possible to Unlock iPhone 4 4.2 while limiting the risks involved with the process.
If you have been keenly following the latest development with iPhone, then you should have realized by now that there is something yummy for lovers of all iPhone 4 to expect in the coming month, that is November. But for those who aren’t conversant with technological advancements, then this article will let you in on the secret of how to unlock iPhone 4 4.2 and the rest of the 4 series. Apparently, there was meant to be a new unlock specifically for all the iPhone 4s this month of October, but that has been delayed until November. However, the drawback is that this unlock will only be effective with GSM and not networks that have speeds higher than this or similar cellular network services.
But while we are still anticipating that process, we can still do with what is available and fairly new in the market, and that is the GreenPoisOn RC5 which was developed by the Chronic Dev Team aka george holtz. After a long wait, it finally hit the market, and all the devices with iOS 4.2.1 can utilize the software to untether them. If you have ever used the RedsnOw 0.9.7 before, you will realize that it requires you to get some blobs (4.2b3 SHSH) which you must save specifically in Cydia. But with GreenPoisOn RC5, you won’t need any of that. This article looks at how to unlock iPhone 4 4.2 and untether it by jailbreaking using the GreenPoisOn RC5 software.
How to Unlock iPhone 4 4.2: GreenPoisOn RC5 for Mac
The version of the software for Mac OS X can be downloaded from the team’s website. Note that you should already be using iOS 4.2.1 before you can proceed with this download. Next, run the GreenPoisOn software on your machine. At this step is successful, you will get a screen shot with the following details:
Get ready to start.
Press and Hold the sleep button.
Continue holding sleep; press and hold home.
Release sleep button; continue holding home.
Follow the above instructions on your GreenPoisOn RC5 screen. In the first instruction, hold the indicated button (sleep) for a period of about two seconds. In the second instruction, do the same for about ten seconds while in the third and last instruction, hold for about fifteen seconds. A hard iphone reset might be necessary to activate iphone firmware.
Proceed to connect your device into the Mac machine. With the iPhone, use the USB cable to enable this connection. Once your Mac has recognized the iPhone, hit the “Jailbreak” button that you will see on your screen. This launches the jailbreak process which is needed to Unlock iPhone 4 on iOS 4.2 firmware version. You might need to downgrade iPhone firmware to a previous version in order to proceed with the process to unlock it.
On successful completion of jailbreaking processg, a Cydia jailbreak app will be installed on your iPhone 4 4.2 device. In this case, there is no need for you to use the “tethered boot” option. This option normally requires you to boot your device before your unlock can be effective but this will be an untethered jailbreak for your device.
How to Unlock iPhone 4 4.2: GreenPoisOn RC5 for Windows
This software was developed after the one for Mac had already hit the market. The procedure is just the same as that for a Mac, the only difference is that you will have to download an appropriate GreenPoisOn RC5 software for Windows.
However, there is one important point you have to remember with the above process. If you have an iPhone 4 that is dependent on a given unlock iphone 4 4.2, the temptation is to update it to a higher version of iOS4.2.1. Please, do not try to do that as such a move will only serve to upgrade the baseband that you are using. A higher baseband version will jeopardize your unlocking efforts.
The GreenPoisOn RC5_2 has the ability to fix some bags, and you can also download it instead of the older version. And in case your iOS4.2.1 is already a tethered jailbreak, (which you achieved with the help of the RedsnOw 0.9.6), you can still install GreenPoisOn and run it over so as to untether your iOS.
