We all know how much Apple hates jailbreaking and with added security in every firmware revision, they make sure to make it more and more complicated for developers to bypass their security.
The company has updated a support document that discusses various disadvantages of iOS jailbreaking. The document enlists various issues that jailbreaking can cause to your device including shortened battery life, device being vulnerable, crashes etc.
As designed by Apple, iOS and iPhone, iPad, and iPod touch are designed to work together reliably. Unauthorized modifications to iOS (“jailbreaking”) can cause numerous issues to the hacked iPhone, iPad or iPod touch. Examples of issues caused by these unauthorized modifications to iOS have included the following:
Instability: Frequent and unexpected crashes of the device, crashes and freezes of built-in apps and third-party apps, and loss of data.
Security vulnerabilities: 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, iPad, or iPod touch on a single battery charge.
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, 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 iCloud and Exchange have experienced problems synchronizing data with their respective servers.
Inability to apply future software updates: Some unauthorized modifications have caused damage to iOS that is not repairable. This can result in the hacked iPhone, iPad, or iPod touch becoming permanently inoperable when a future Apple-supplied iOS update is installed.
Apple strongly cautions against installing any software that hacks iOS. It is also important to note that unauthorized modification of iOS is a violation of iOS end-user license agreement and because of this, Apple may deny service for an iPhone, iPad, or iPod touch that has installed any unauthorized software.
Frankly, apart from our love for jailbreaking, these points are absolutely valid but let us say we can not help ourselves to install tweaks, themes and other Cydia packages that are not available in the official App Store.
Other than that, if its not for jailbreaking, Apple’s iOS might not have seen such level of security that it currently owns. Every time they release a jailbreak, it gives Apple another change to add more security to their operating system.
Remember, jailbreaking of phones was declared legal and there is nothing Apple can do to officially stop it other than patching the exploit in the next firmware revision.
