New to Jailbrake

[jdusoccer12]

Ok i am new to the whole jailbroken things. I was just wondering what it is, and how to do it, and can i undo it at anytime? Does this void my warranty? I am kind of wondering because i am tired of the trouble with 2.0.1 and i just wanted to try this out.

Jailbreaking isn't going to fix bugs with 2.0.1, all its going to do is add Cydia or Installer(when released) to add unauthorized applications.

It may not give you installer by default but it does give you cydia. If you want installer I can give it you, it was leaked and I managed to grab a copy of it so I have it now.

winpwn 2.0.0.4 and pwnage tool 2.0.2 both jailbreak and give you installer
