> Can anyone explain why iOS jailbreaking info would be worth more than $1m to the NSA?
Jailbreaks are essentially reliable exploits, so any "jailbreak" if tweaked would also be a good way of installing malware or an implant in NSA parlance. This is also not just one vulnerability it's several, a remote vuln to get on the phone, a sandbox escape, a info leak to calculate the ALSR slide and a kernel exploit. This is a considerable amount of work, I'm guessing a month or so of fuzzing and manual testing, and 2 months to develop the jailbreak/exploits.
