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?
