Apple hacked devices
Apple has posted an support document that details problems encountered with jailbroken iPhone and iPod touch devices. The company believes the hacking process is "a major source of instability, disruption of services, and other issues." The support article is intended to better explain the risks of installing software that modifies the iPhone OS, and discourages doing so. Problems common with jailbroken iPhones include device and application instability that causes unexpected device crashes, loss of data, and crashes of applications.
The article also believes modifications to the OS can cause dropped phone calls, slow or sparse data connections, and delayed or inaccurate location data, as well as accelerate battery drain. Jailbreaking an iPhone or iPod touch can also be the source of service disruptions such as visual voicemail, YouTube, Weather, Stocks, push-notifications, and problems syncing with MobileMe and Exchange.
Apple support also suggests the process causes security compromises that can allow hackers to steal personal information, damage the device attack the wireless network, or introduce malware and viruses. Some modifications can cause damage to the OS that is not reparable and prevents the device from being updated.
Unauthorized modifications of the iPhone OS is a violation of the iPhone end-user license agreement, and Apple says it will refuse to service the device.
