(adsbygoogle = window.adsbygoogle || []).push({}); Jailbreak for iOS 4.2.1

My first jailbreak was using this program and on this firmware with my Iphone 4, hope you all enjoy.

To clear some things: This jailbreak support iphone 4 3GS 3G and ipod non-MC Model. This jailbreak is untethered for some idevices and tethered for some, heres the list:

Untethered
Iphone 3GS 3G and older ipod touch models
Tethered
4th generation devices (ipod touch 4th gen and iphone 4)

Tethered means that you have to connect the phone to your computer every time you turn it off or needs to reboot it you have to connect it to the computer.

These are the files you need:

Itunes 10.1 [go to apple.com and download]

1. Start itunes 10.1 and have it running in the background
2. Start Redsn0w
3. Hit browse and browse for your downloaded .ipsw file
4. Hit next and it will prepare the jailbreak
5. Select install Cydia and press next
6. This is a page that tells you to make sure your Idevice is plugged in and turned off
7. Now it's work time! Whene you press next you have to get ready and hold the power button for 3 seconds. After that press the home button without releasing the powerbutton and hold them both for 10 seconds. Thene release the power button but keep holding the home button for 15 seconds. The instructions also comes up on the screen. This is called putting your device in DFU-mode.
8. If done correctly Redsn0w will recognize your device and the jailbreak begins, go grabb a sandwich, and when you come back, you will have a jailbroken Idevice!

Notes:
If Cydia doesnt open, reboot your device and it will be working. If you have tethered jailbreak you will have to do these jailbreak steps again to boot up, but instead of checking "install Cydia" you check "just boot tethered now"

Me, for writing this thread

Happy holidays <3

Yeah, if i do that wont i lose all my PAID apps ? :/

Not if you have synced it with itunes before, then when you restore it the apps will install by them self

I restored my PC so i have not synced it with iTunes

Sync it now! And if you have paid for the apps, the payment is saved on your itunes acc so you can just download the apps for free again of itunes

It doesnt give me the option to sync anymore :/
There is 1 button but nothing happens when i click it.

i Did the CFW hack but thanks to recent update cant
change patch, if some1 would better xplain how to do this with, phone would be greatful thnks

Sorry to say this bro, but I think you need to get a new ipod


Your first post, con gratz on it being in the wrong section, wrong thread and totally random :Y:

No, i synced it now, and whenever im still putting it into DFU it flashes and turns off :cry: i just got a new ipod...

Another reason i hate the bahamas everything works to the fact that my phone isn't luck but just can't make calls.
