Jailbreaking your iPhone is a way to work around the limitations built into the operating system of the phone. This gives you a bit more free range in customizing your phone and settings options, not to mention the ability to use Cydia for apps. Jailbreaking sounds difficult and confusing, but it is actually very simple and can be performed by anyone that knows how to sync an iPhone to the computer. If you have a Verizon iPhone, I'll walk you through how to jailbreak the phone; but first we should discuss some things you may want to consider before doing so.

    Jailbreaking is legal, but is frowned upon by Apple and may void the warranty for your phone. While the benefits of jailbreaking can be great, it has to be performed at your own risk. In rare cases, jailbreaks and unlocks that aren't performed correctly or for the right software have caused the phone to lock up and become inoperable. In addition, viruses or faulty programs are possible because none of the software or apps are certified by Apple, nor are they required to go through the rigorous approval process. If you do encounter a virus or faulty program, it can affect the function of your device. This doesn't mean that you shouldn't jailbreak your iPhone 4, just that you should be cautious about it and do your research. It wouldn't be responsible to present you with a way to jailbreak Verizon iPhone without warning you about the risks.

    Why the Verizon iPhone Jailbreak is Different from an AT&T iPhone Jailbreak

    Many AT&T iPhone users wanted to switch to Verizon with their current iPhone 4 when Verizon started offering the popular smartphone. Unfortunately, they were disappointed to find out that the phones were not compatible with the Verizon network. Verizon iPhone operates on a CDMA network, whereas AT&T uses GSM. Although the Verizon iPhone looks almost identical, some internal components of the phone had to be rearranged to accommodate a CDMA signal. Due to this, a few structures of the phone were slightly shifted. This caused a headache for iPhone 4 case manufacturers who had to make special cases for Verizon iPhone. It also made jailbreakers scramble to develop a jailbreak that was safe for the CDMA phone. Any jailbreak that you perform should use software that is specific to and tested for your model and iPhone software to prevent damaging your device.
