Be very very carefull. Because there are so many fake web sites came out recently. Do not trust names like quickpwn.com. There sites pretend to be DevTeam. Applications that those sites give you might be dangerous for your iPhone. Some sites ask for donations. Remember DevTeam don't do it.
There is only one DevTeam's site: http://blog.iphone-dev.org. When I publish news about some new version of QuickPwn, WinPwn, PwnageTool and etc, I use links from DevTeam's site. Everything else could be harmful fake.
There are so many tools, some for Mac OS, others for Windows, different versions... Complicated. So let's summerize a little bit.
If you have iPhone 3G, you'll be able to install 3-rd party non AppStore applications (through separate applications called Cydia and Installer) and run these applications. If you have old iPhone, in addition to that you'll be able to unlock the device (use with any carrier).
There are two methods: quickpwn and custom firmware method. First one is for quikly pwning and jailbreaking the device without restore. You should use it if you have unlocked device or an AT&T contract.
If you are Windows user:
Go for WinPwn. The current version is 18.104.22.168 (also called 2.5 beta-2). Download here. It supports both iPhone and iPhone 3G, firmwares 2.0, 2.0.1, 2.0.2. You can use either quickpwn or custom firmware method.
There is a separate QuickPwn tool for Windows. The current version is RC3. Download here. Do you need it? Yes, if you want to quick pwn and you do not like WinPwn (or you had problems with it).
If you're using Mac OS:
Go for PwnageTool. The current version is 22.214.171.124. Download here. Works with 2.0, 2.0.1, 2.0.2 firmwares using custom-firmware method.
There is a version of QuickPwn tool for MAC OS. The current version is 1.0.0. Download here. It works only with firmware 2.0.2. Do you need it? Yes, if you want to quick pwn.
QuickPwn is not a replacement for PwnageTool, they are different tools and provide different features, QuickPwn is for quickly pwning a device, whereas PwnageTool is designed to custom build and tailor the ipsw production process, both tools will be actively developed in the future.
Recently a new project has been started, called XiPhone. It will be based on XPWN. So functionality similar to WinPwn and Pwnage will be present (jailbreak, unlock, etc). In addition to that developers plan to include:
Auto downloading of stock firmware files from apple’s site (no need to hunt for it then select it)
Wizard based modern GUI (created with .net 2.0), and Vista Style UI.
Export of firmware settings so users can pass around an XML file which contains a configuration that works for them.
Auto updates to the XiPhone software.
Community based wallpapers used for Bootscreen, Restore screen and others
Enabling / Disabling of options available based on the device you select.
Unfortunately, only Windows platform users will be able to use XiPhone.
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.
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:
