sbsetting里的“apple killswitch”是什么意思

apple killswitch功能，是为了防止apple使用此功能从你的iphone上删除apple不喜欢的程序。 原文：steve jobs confirmed a widespread rumor in a wall street journal interview today. he admitted that the iphone has code inside it that routinely checks back with apple to see if any downloaded software has been blacklisted. this also enables apple to remotely disable any malicious programs at their discretion. apple raised hackles in computer-privacy and security circles when an independent engineer disc****ed code inside the iphone that suggested iphones routinely check an apple web site that could, in theory trigger the removal of the undesirable software from the devices. mr. jobs confirmed such a capability exists, but argued that apple needs it in case it inadvertently allows a malicious program one that stole users’ personal data, for example to be distributed to iphones through the app store. hopefully we never have to pull that lever, but we would be irresponsible not to have a lever like that to pull, he says. 翻译内容：乔布斯承认iphone中代码能定时回传数据给apple，apple可以得知是否用户下载了被列入黑名单的应用程序。这使得apple可以凭借自己的意愿，远程让这些软件失效。 这是由一位独立工程师在iphone中发现的，iphone会定期检测(访问?)apple的网络站点，这就使得，apple可以将其不热衷的软件从客户的iphone上移除成为可能，这**激怒了注重电脑隐私和安全的人群。 乔布斯承认这个功能的存在，但反驳道：apple需要这个功能是因为有可能有恶意程序不经意地通过app store侵入iphone可能会窃取用户的私人信息。希望我们永远都不必启用这个功能，但如果我们没有这样一个可以启用的功能的话，我们就是不负责任的公司了。
