i am wondering how hackers create jailbreak.I know what means Userland exploit and kernel exploit.I know that when I have userland exploit I need to find kernel exploit.But I really don't know what means "payload", "ROP","ROP Payload","payload".How this interconnect with userland and kernel exploits??? Can somebody do "scheme" for this? Thanks

ROP is a form of programming it is used because well no other method will work as of iOS 4.3. The payload is what you use when exploiting so you find a say kernel exploit in vm_map_copyin() like mdowd that you can use in an app, your payload is essentially the code that patches and runs your code.
