I was recently given an Apple iPad and its software restrictions limit what I can do with it (installing software from other sources, customization, file explorer, etc). I know that the solution would be to "jailbreak" it, that is to say to gain root access on it.
How do I perform a jailbreak ? As most apps are created for other operating systems, I would appreciate a software recommendation.
I run Ubuntu 12.10 and own a first generation Apple iPad with iOS 5.1.1.
