I sure hope Apple can't force an uninstall of apps I've already downloaded and installed... This makes me distrust the auto app update feature of iOS 7.
1. The App Store approval process (and app sand boxing) is so good that no malware made it through that needed the kill switch. Or,
2. Malware has made it out to customers, and the kill switch was used. However, Apple certainly isn't going to publicize that fact, and the malware author probably isn't going to either.
