Help with jailbreaking and Cydia for iPhones, iPads, and iPod touches.

Question

Hi. I was wondering how you create a new jailbreak.

What tools (software/hardware) do you use?
What is the recommended knowledge (i.e. study these books first)?
How do you find a new exploit?

I most probably won't have the time nor the skills (sigh) for serious development, but still I am interested and curious about the theory, and I would like to learn more.

Any suggestion is appreciated. Thanks!

For those interested, Stefan Esser, also known as I0n1c, the hacker behind the iOS 4.3.1 untether has created an amazing presentation on the latest iOS jailbreak techniques. Esser made the presentation for Black Hat last month.

As you know, yesterday there was MyGreatFest (http://mygreatfest.net/) in London Some presentations can be viewed here The presentations do not seem to be as good and as informative as the one of I0n1c, but still they are something useful to have as a reference.

Go read up on theiphonewiki.com, if you can digest all that info then go speak with the hackers on IRC

A couple more things to look into for anyone interested in userland jailbreaking would be this analysis of JailbreakMe along with the JailbreakMe code itself.

There's also a book coming out next year that should be pretty good: iOS Hacker's Handbook.

And you can also start with Wikipedia.

I always tell people if you have to ask where to start reading, you do not have what it takes to succeed at this

It's ok to ask for tips on where to learn about these things for fun, even if (as the asker said) they might not have the time required to develop the skills for actually finding exploits. :)

well you have to start somewhere

Luckily we have people like you who know where to start and what to do without asking, @dhlizard. I know I am no good at all (I think I was clear on that), that's why I have to ask :-)
