If you are considering whether or not you want to jailbreak your iPad, you will want to weigh out the pros and cons to see if it’s worth it. The good reasons to jailbreak your iPad are so you can get apps that aren’t found on the App Store such as from Cydia and other resources. This will give you a lot more options when it comes to customization such as being able to choose different skins, sounds, adding apps to your home screen and how apps shut down. You will also have more access to be able to control your iPad such as allowing devices to communicate with each other.
The best reason to not jailbreak you iPad is that is that it will void the warranty and leave your iPad unprotected. Since jailbreaking is a complex technical process, you risk bricking your iPad which will make it useless. If you are able to jailbreak your iPad and it still works, it is left at a higher risk for attack through viruses and malware. It also has a tendency to crash more often. Finally, after you jailbreak your iPad the ability to update it will become much more difficult because you have to erase the jailbreak before you update, then re-jailbreak it after you update. Because erasing the jailbreak erases all the apps and customization, you then have to reinstall those as well.
