neat bug, although only the iPhone 4 and earlier would be unpatchable for it, and those devices are pretty much stuffed from a security standpoint anyway as they&#x27;re vulnerable to the old DFU mode jailbreaks...<p>I was kind of thinking more of examples of malware where people were actually using the lockdown of the OS to stop users removing it, but hey I said exploits and that&#x27;s an exploit.
