Maybe, maybe not. When apple releases a new version, iTunes will ask if you want to install it. Say NO. Then start reading your favorite hacking site. The last couple of updates had 2 distinct ways to do it. The first step is to always remain calm. You have a working phone that is jailbroken with your favorite apps, themes, etc. There is no reason to let the excitement of a new version ruin that for you. New versions are severely over hyped. I often wish that I was back to version 1.1.4. Read those hack sites because the two ways to do it are different. They are

1. update your new phone through iTunes.
2. Download and run quickpwn after the update.
3. install the JB apps of your choice through Cydia.

or

1. download (but do not install) the new update from Apple.
2. download the pwn tool.
3. use pwnage to modify the Apple update.
4. use iTunes to update the phone with the modified version of the update.
5. install the JB apps of your choice via Cydia.

EVERY time a new update comes out, many people will jump the gun and screw it up and post that their iPhone has been screwed up. Sometimes they miss a tiny step, sometimes they are complete dopes and skip all of the warnings. That's why you wait a week (at least a few days) to see what problems popped up and what they did wrong so that you don't do the same. Nobody at work buys you lunch because you are the first with a new update. None of your neighbors give a crap whether you have the new update or not. It's 90% ego and 10% dream of problems being fixed and new features added. There are advanced ways to update too and they don't come with a prize either. Stick to the basics.

A lot of people know how the new 2.2 will be hacked. Still, the pwnage tool will not be built until the final version is released. There will be changes on it that are not on the current versions. Then it will need to be tested on a variety of different computers running a variety of different operating systems in a variety of different configurations.

Typically, but not always, a Mac version comes out before a Windows version. More than likely a pwnage tool will come out before a quickpwn version comes out.

How did you do you JB your phone this time? Did you use quickpwn?
