Apple Document Says: Jailbreaking is Bad For You!


Looks like Apple has released a document on the state of “jailbreaking” and why this can harm your device. This “unauthorized modification” of iPhone OS can lead to a plethora of problems according to Apple. For those who have jailbroken your iPhones, let’s hear how many issues you have run into.


With my previously jailbroken iPhone 3G, the installation of Winterboard slowed down my phone big time. Uninstalling Winterboard is one of the best ways to speed up your iPhone. Also, I’ve noticed that my iPhone 3GS battery life has been affected by my current jailbreak (click here for my 7 minute iPhone 3GS jailbreak video tutorial). Although not by a lot but enough for me to notice. Personally I think the pros outweigh the cons with all the fun stuff Cydia offers.

Here are examples of issues you may run into by “jailbreaking” your iPhone according to Apple:

Device and application instability: Frequent and unexpected crashes of the device, crashes and freezes of built-in apps and third-party apps, and loss of data.

Unreliable voice and data: Dropped calls, slow or unreliable data connections, and delayed or inaccurate location data.

Disruption of services: Services such as Visual Voicemail, YouTube, Weather, and Stocks have been disrupted or no longer work on the device. Additionally, third-party apps that use the Apple Push Notification Service have had difficulty receiving notifications or received notifications that were intended for a different hacked device. Other push-based services such as MobileMe and Exchange have experienced problems synchronizing data with their respective servers.

Compromised security: Security compromises have been introduced by these modifications that could allow hackers to steal personal information, damage the device, attack the wireless network, or introduce malware or viruses.

Shortened battery life: The hacked software has caused an accelerated battery drain that shortens the operation of an iPhone or iPod touch on a single battery charge.

Inability to apply future software updates: Some unauthorized modifications have caused damage to the iPhone OS that is not repairable. This can result in the hacked iPhone or iPod touch becoming permanently inoperable when a future Apple-supplied iPhone OS update is installed.

Is your iPhone jailbroken? Are you happy with your jailbreak? Are you scared to jailbreak?

    The banner at the top of my phone (where the time used to be) says BITE ME JOBS. Nuff said.

    Who cares… This is getting very repetitive Apple. Every so often Apple is complaining about Jailbreaking, its not going to stop. Lets hope not.. .. lol 😛
    We pay Apple and Rogers (Rogers really has nothing to do with Jailbreaking) enough money for their products that once its mine, I can do whatever I want! 🙂

    I personally have not experienced many problems jail breaking my 3GS. I have noticed that the battery life is not as good but in the end, who cares, i really do enjoy all the possibilities that a jailbreak can represent and that in itself outweighs the battery performance issue.

    I agree with Dusty, once we pay for it, its ours to abuse and use to whatever we see fit.

    Jailbreaking itself has no effect on my iPhone as far as I can tell but some of the apps do affect performance. The only jb apps I have permanently installed is voipover3g and mobilesubstrate. Anything else I install when I need it and uninstall when I don't. Battery life and the rest unaffacted. I run some pretty intense graphics like x2 football no worries.

    Bottom line it depends on what exactly it is you are running on your iPhone

    I didn't Jailbreak my phone and don't plan to, but I have nothing against those that do. I personally am happy with what my 3GS offers out of the box and haven't seen benefits that appeal to me. That said, to those that are jailbreaking, it's your hardware to use as you like. More power to you!

    Yup. I’ve tested it a few times, and would happily put real money on this:

    Jailbreaking DOES NOT do any of those things. The apps you install could; but that applies to AppStore apps as well. Install a push notification app(using push) and tell me that doesn’t affect battery life.

    If you jailbreak, you DO need to pay more attention to what you install, and be aware that apps may be buggy. However, if you have a problem, just uninstall the last app you installed. Done.

    With winterboard, yes, it will slow down a 3G phone (though not noticably a 3GS). You can get around that by installing Winterboard Settings, and having it only run in Springboard, not your other apps.

    And THAT is the advantage of jailbreaking: YOU control how things work on your phone.

    We’ll see who releases an SMS patch (other than shutting off SMS entirely) first… But so far, apple isn’t really doing a bangup job of security. Encryption was cracked in minutes, and now this?

    The only things I use my jailbreak is winterboard an categories.
    I hate looking at that stupid globe all the time. I would much rather
    look at Megan Fox with dimmed icons. Apple needs to do something
    about customizing your phone a bit more. The other thing is to be able
    to add a contact while in the calendar (I guess people only with MS Exchange
    need to make appointments?).

    I've been using my 3gs with redsn0w 3 jailbreak. so far, it's great. Much mroe stable than any versions undur os2. I wonder if Apple might update their software with some sort of ecm to actually do harm to jailbroken iphone.s
