How to Unlock iPhone 4 for Free with Software on Mac
If you have an iPhone 4 that is locked to a specific carrier, you might be wondering how to unlock it for free. Unlocking your iPhone 4 can give you the freedom to use any SIM card from any network, as well as access to more features and apps. In this article, we will show you how to unlock iPhone 4 for free with software on Mac.
What is Unlocking and Why Do You Need It
Unlocking your iPhone 4 means removing the restriction that prevents it from working with other carriers. This restriction is usually imposed by the carrier that sold you the phone or the one that you signed a contract with. Unlocking your iPhone 4 can have many benefits, such as:
Using your phone with any SIM card from any network, anywhere in the world.
Saving money on roaming charges when traveling abroad.
Switching to a cheaper or better plan from a different carrier.
Increasing the resale value of your phone.
Accessing more apps and features that might be blocked by your carrier.
However, unlocking your iPhone 4 can also have some risks, such as:
Voiding your warranty or violating your contract with your carrier.
Bricking your phone or damaging its software if you use an unreliable or incompatible method.
Losing some functionality or compatibility with certain networks or services.
Therefore, before you decide to unlock your iPhone 4, you should weigh the pros and cons carefully and make sure you understand the consequences. You should also backup your data and settings in case something goes wrong.
How to Unlock iPhone 4 for Free with Software on Mac
There are many methods and tools available for unlocking iPhone 4, but not all of them are free, safe, or compatible with Mac. One of the most popular and reliable software for unlocking iPhone 4 for free on Mac is Ultrasn0w. Ultrasn0w is a jailbreak app that can unlock iPhone 4 running on iOS 7.1.2 or lower. However, Ultrasn0w only works with certain basebands (the firmware that controls the cellular modem of your phone). To check your baseband version, go to Settings > General > About > Modem Firmware. The basebands that are compatible with Ultrasn0w are:
01.59.00
04.26.08
05.11.07
05.12.01
05.13.04
06.15.00
If your baseband is not one of these, you will need to downgrade it using another software called Redsn0w. Redsn0w is another jailbreak tool that can also change your baseband to 06.15.00, which is compatible with Ultrasn0w. However, this process is risky and irreversible, and it might cause some issues with your GPS and battery life. Therefore, you should only use Redsn0w if you have no other option.
To unlock iPhone 4 for free with software on Mac using Ultrasn0w (and Redsn0w if needed), follow these steps:
Jailbreak your iPhone 4 using Evasi0n, a simple and easy-to-use jailbreak tool that works on Mac and supports iOS 7.1.2 or lower. You can download Evasi0n from here and follow the instructions on the website.
If your baseband is not compatible with Ultrasn0w, download Redsn0w from here ec8f644aee
