Your device May Lose Stability
Jailbreaking is a hack and there are unexpected things that could happen because of that. It’s possible, after jailbreaking your device and installing applications via Cydia – the unofficial App Store, your device may become buggy and slow.
It may even crash.
Now, for power users and those willing to troubleshoot, this probably won’t be too much of an issue. However, for the average person, it can and probably will become a headache.
For many of you, having a stable iPhone / iPad will be more of a priority then having a customized one.
Updating Is a Pain
While the stability issue might not be one that affects everyone that jailbreaks, the pain in the rear end known as updating your jailbroken phone does. If you’re the kind of person that wants the latest and greatest software right off the bat, jailbreaking might not be fore you.
When Apple releases an update, you will have to wait for the devs to either release a patch or a new jailbreak for your iPhone. When it comes to smaller iOS updates, it’s usually a fast process.
However, when it comes to larger updates like iOS 6.1 it takes awhile. So, if you’re the impatient type, keep this in mind.
And once you get the update, your headache might remain as you’ll need to re-install the jailbreak and all of the apps that you downloaded from Cydia. There are definitely tools out there that can help you restore, but it’s still going to take some time.
In other words, it’s not the seamless process you might expect from an official update.
