That'll be a cold day in hell. You can jail break pretty much all iOS devices but you'll never be able to side load unscanned apps as well as run Apple's secure enclave; these are incompatible technological goals. For everybody saying various Governments will force Apple to do this they simply won't. Apple doesn't have a monopoly in which regulatory leverage can be applied but importantly, Government hardened iPhone OS is now the ubiquitous phone for most Government personnel in a very large list of countries.
Denting this secret dents Government security.
The iOS market share is small, anybody not being onboard with Apple's was of doing things can buy any other mobile device/OS.
If I didnt want the government snooping on me an iphone is not what I would get,
do you remember some us government organization trying FBI? to get apple to include something to unlock a phone, they were practically shouting it from the rooftops, it was all over the news. If they really wanted it they would of been a lot more quiet with the paperwork
FBI (shouting) "dont get an apple phone we can't break into it' (hint hint)
apple (shouting) "we will never compromise our security" (buy our phones if you care abotu security)
FBI (yes you terrorist organizations dont get those IOS devices we cant see whats going on with them)
(*)
the thing was at the time, they could of easily gotten a company to unlock it for a price (I think perhaps they did in the end), so when apple at the time saying it was impossible to unlock them it was a proven lie
2/ you will also see here
http://zerodium.com/program.html they pay less for a IOS full exploit than an android one, ergo its easier to break into IOS
3/ google is not really in china as they wont agree to china governments rules, apple OTOH has no problems operating there, I wonder why that is
FWIW I have a IOS device, as I dont care if the government spies on me, but I'm not naive enuf to believe that my devices are secure
(*)I was talking to my GF about something similar the other day, about area 51, she was saying if they had alien stuff it would be there, Im like thats the last place, sure its very secure, like a lot of US bases but its also got a lot of eyes pointed at it, how many hackers have tried to break in over the years.
better to have it at somewhere else with the same level of security but anonymous. Not that I believe the US government has any alien stuff
