In a newly published support document, Apple has blamed a number of iPhone and iPod touch issues on jailbreaking. The article, entitled “Unauthorized modification of iPhone OS has been a major source of instability, disruption of services, and other issues,” describes a number of issues dealing with instability, reliability, security, and more. In particular, it claims jailbreaking can disrupt Visual Voicemail service, cause “frequent and unexpected crashes of the device,” lead to “accelerated battery drain,” and result in “slow or unreliable data connections,” all problems experienced first-hand by iLounge editors on iPhones and iPod touches which have never been jailbroken. After strongly cautioning against “installing any software that hacks the iPhone OS,” the article notes that “unauthorized modification of the iPhone OS is a violation of the iPhone end-user license agreement and because of this, Apple may deny service for an iPhone or iPod touch that has installed any unauthorized software.”
