Jailbreaking noob! Questions

[Brandon]

How do I start off. I want a little explanation on where I start off and how I progress in terms of what links I should go to and what I should do first till last in the process. Also, should I jailbreak? What are the benefits?

What does "Installer" and that other application QuickPWN installs do?

Also, what are some cool applications that would make me want to hack my iPhone? Is it worth it? Does it screw up your phone?

Installer is rarely used anymore.
Winterboard is the DEAL
quickpwn is a tool used for jailbreaking.
It will not screw up your phone, you can always restore.

quickpwn is the computer program used to jailbreak and unlock your phone. Installer and cydia are like the app store, they offer apps such as video recording, copy and paste, mms and SMS apps, themes for the keyboards lockscreens notepads home screens, basically any thing you can think of that apple doesn't and or won't offer.
And no jailbreaking will not hurt your phone.

I'm fairly new to it all myself but I am definately glad mine isn't restricted!!!
Good luck and feel free to ask around and search, great people here!
