These are instructions on how to jailbreak your iPhone using PwnageTool 4.1.2 for Mac OS X. If you need unlock and you have not updated to iOS 4 you will be able to preserve baseband and unlock iPhone using ultrasn0w.

This guide will work for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 3G, iPod Touch 4G, iPad and AppleTV. Just use the right firmware and select the right device (step four).

Step One
Make a folder called “Pwnage” on the desktop. Now you need to download there PwnageTool 4.1.2 from here and iOS 4.1 firmware from here.

When downloading the IPSW file, it is best to download it with Firefox since Safari often auto extracts it!

Step Two
Double click to mount PwnageTool then drag the PwnageTool icon into the Pwnage folder.

With internet tethering enabled you can use iPhone internet connection on you desktop or notebook. Here is a quick tutorial for experienced users. For everybody else – just wait for the new version of PwnageTool or some other utility.

Here it is:

A bsdiff patch to apply to CommCenter in 3.1.2 to re-enable tethering is available here for the 3GS and here for the 3G. It’s just a 2-byte patch as shown below (and an appropriate readjusting of the mach-o’s codesign hash):

USE THIS AT YOUR OWN RISK! Your carrier may end up charging you for unauthorized tethering access.

Update #1 It looks like a lot of people have been looking at CommCenter lately because IRC user CleanAir had a similar tethering patch. Meanwhile over in the 2G CommCenter, WhiteRat and geniusan have patched in native MMS support for that platform. Kudos to CleanAir, WhiteRat, and geniusan for digging into CommCenter and coming up with patches!

Update #2 A few tutorials have started to pop up. Eventually this will be made a part of the normal PwnageTool flow but for now this is best left for the adventurous users out there!

Thanks to Dev Team and the porting work of Jay Freeman as well as the authors of 3Proxy, it is now possible to “tether” your iPhone 3G and use its Internet connection on your laptop.

Warning – Tethering your iPhone is against the iPhone data plan terms. AT&T could slap you with huge fees if you overuse this. I recommend only using it during emergencies.

Here is a basic plan (by the way, this should work for old IPhone also):

• Jailbreak your iPhone 3G
• Install 3Proxy and Terminal
• Create an ad-hoc Wi-fi network using your laptop
• Join the network with your iPhone
• Find the iPhone’s IP address
• Open Terminal and run the proxy program
• Open Safari on your iPhone and open a web page
• Configure your browser to use the proxy

Later we’ll discuss it with more details.
