to do it on the device itself is easy if you have a code signing exploit but thats the problem those are not easy to come by and one can pay 250k or more for one of those, so your alternative is to have some one do it remotely from the source and that takes axcess to albert and that is why it costs around 200 bucks,that is apples server and if they get caught in there you wont be seeing them for a while.
