...a bootrom (?) jailbreak? I'm not sure if it's called a bootrom jailbreak, but if it isn't then I mean the other type which isn't userland. Can anyone clarify the difference between the two? My understanding is that with a userland jb even updating iTunes might kill your jailbreak, whearas with Redsn0w, it won't. Surely Redsn0w type jailbreaks are more reliable? Is there any difference in the overall performance of a jailbroken phone depending on the type of jailbreak used? As you can probably tell I don't know a great deal about this, but if anyone can help me understand this a bit better I would really appreciate it. Thanks.
