How to jailbreak iPhone 3G any firmware untethered

Note that I wrote the following tutorial for beginners to to make it easy so sorry if I sound a bit simple at parts 😛

Hello, in this post I will show you how to jailbreak your iPhone 3G (making this for a friend). I have a jailbroken iPad 2, iPhone 4, etc… But today I screwed up my iPhone 3G (yes i still use it) 🙂 so while I’m jailbreaking it again I thought I would explain it. It actually took me a while to find a version of redsnow that is compatible with the iPhone 3G about 2 or 3 years ago 😛 , so let’s get straight into it:

What you will need:
• Resn0w which can be downloaded here

(save it and extract the .zip to your desktop)

• The IPSW for whatever version iPhone you have. To see what version you have go to settings (on your iPhone) general, about and scroll down to Version. I have 4.2.1 so I need to download the IPSW for 4.2.1. To do that, go to felixbruns.de and click on iPod firmware

Now where it says iPhone in the second drop down box, scroll down to iPhone 3G followed by your firmware version. So for me I would select this one because I have an iPhone 3G on 4.2.1.

Save this IPSW to your desktop where you extracted redsn0w

Now we have everything, let’s get started.
Go to where you extracted redsn0w (mine is on my desktop)
Right click and make sure to “open as” ->;;;ADMINISTRATOR!

right click on redsn0w.exe and select “run as administrator” and allow

Now redsn0w will open. click “browse
” and select the .IPSW file you downloaded earlier

Click “open”

It will say processing firmware and a bunch of other stuff, just wait till it says IPSW successfully identified and hit next. More loading…
Then choose the addons you want. DON’T UNCHECK CYDIA. I am just going to have install cydia, enable multitasking, and enable home screen wallpaper checked. Then click next.

Now plug your iPhone into your computer, THEN hold the power button and turn it off, THEN click next and follow the instructions on the that page. If you miss it or just want to see what needs to be done on the next step then click next, read what you have to do then click back and next when your ready.
(this step puts your device in DFU mode) sorry if thats confusing, comment if your stuck.

Once redsn0w says jailbreaking… Waiting for reboot etc you can let go of the home button. Your iPhone will now show lots of “random” words etc and then this:

Wait for your phone to reach the slide to unlock screen.

Redsn0w should now say “done” on your computer and you can now click finish.
Open Cydia from your SpringBoard (there will be an app for it) to finish the setup.

That’s it! Enjoy your now jailbroken iPhone 3G

After jailbroken:

How to reset your iPhone/iPad/iPod home button

How to make your iPhone/iPod/iPad Homebutton feel like its new.

My friend showed me this and I couldnt believe it so I thought I would upload I for others to see.

Does your home button get stuck, is hard to press or just doesn’t have that new click anymore? Well heres how to reset it. (trust me it 100% works but I have only ever tried it on an iPhone 4)
1- go to ANY app that came PREINSTALLED on your device. I use the weather app.
2- Once in the weather app hold the power/sleep button until it comes up with slide to power off. DON’T slide to power off.
3- Hold the home button until it exits to the home screen.

And there you have it! It might not work for everyone but I DEFINATELY noticed a difference and my iPhone now feels like when I just bought it.
Thanks for reading! 🙂
