Using QuickPwn does not update the firmware itself, this tool is designed to ‘Pwn’ (the ability to install future custom non-Apple firmwares) , ‘Jailbreak’ and install Installer and/or Cydia on a given device. If your device is running 2.0.1 and you QuickPwn it, it’ll still be running 2.0.1, although it will now be Pwned and Jailbroken. It will also activate (not unlock) devices that are being used outside of their intended territories and cannot be activated using iTunes.
If you want to update to 2.0.2 then use the normal iTunes update to get to 2.0.2 and then use QuickPwn to Pwn, Jailbreak and Activate, remember that the 2.0.2 update includes a baseband update for the 3G iPhone, so depending what your long term intentions are for the phone, update wisely, of course in the upcoming PwnageTool application you’ll be able to create a custom ipsw without the baseband update enabled.
Some people are complaining about the iPhone 2.0.2 update killing their ability to actually make calls over 3G. Among the people who suffer from no-calling-itis is one guy who took his phone to AT&T and had them swap out the SIM, which somehow fixed the problem. If you're getting "call failed" on 3G, try switching back to 2G in Settings -> General -> Network and making the call again.
LockDown v3.0 is out with a lot of improvements. If you need to be able to lock certain apps with a password so you can hand your phone off to someone else for a bit, this is the app for you. There is also a lost password protection.
Avaliable in Cydia installer for iPhone with firmware 2.0 and above.
AppBackup is a program for the iPhone/iPod touch that lets you back up and restore the saved data and settings for your App Store apps.
To back up one app, open AppBackup, select the app, and then select Backup. To restore an app, select it and then select Restore. (If there is no restore option, then it hasn't been backed up yet.) To back up all apps at once, tap All at the top-left of the screen, and select Backup. To restore all apps that have been backed up at once, tap All and select Restore. (You must have at least one app backed up in order to see this option).
Avaliable for free via Cydia Istaller.
A jailbroken iPhone or iPod touch running iPhoneOS 2.0 or later, with Cydia and at least one App Store app.
DevTeam created a quick solution for jailbreaking an iPhone. It is called QuickPwn. It is in beta, so be careful. It will allow you to pwn (jailbreak) your device very quickly without restoring!
Who should use this tool? This is for those that are not planning to restore. It’s not clear what the activation state is after the process therefore, I only recommend this for those that have a contract carrier or an unlocked phone already.
If you are on a stock device and using AT&T or a contract carrier, this is the perfect jailbreak for you. You will not lose your contacts or have to do any backups. Finally, if you are going to restore anyway, especially if you need to unlock a 2g, you may as well use winpwn or such.
Currently QuickPwn requires your device to be running version 2.0.1 of the iPhone/iPod firmware. And it runs only on Windows. This requirement will change in a subsequent release.
Once installed and customized, it allows you to download data off the Internet and store it on your iPhone or iPod touch local disk. You can download mp3 files, zip archives and much more. It was avaliable for old firmwares (1.1.4 and below). Now 2.0 users can use it too. Avaliable through Cydia Installer.
After WinPwn 126.96.36.199 release users are able to try Insteller 4 beta. The repositary mechanism was changed and applcations should support new firmware (> 2.0), so old ones will not work. Here is the list of new repositaries:

Just a reminder, Installer is in beta. So we adwise you to use Cydia.
