How to Jailbreak & Unlock iPhone 2G v 3.0

iPhones that have been Jailbroken & unlocked sell better on eBay, so I decided to Jailbreak my old 2nd generation iPhone OS 3.0 before I put it up for auction. This is the second time I Jailbreak my iPhone after writing my original iPhone Jailbreak guide a couple years ago.

Here’s how I did it:

[Note: This iPhone Jailbreak guide is intended for 2nd generation iPhones with 3.0 firmware or below ONLY. For instructions on jailbreaking other iPhone versions, visit the ultimate guide to jailbreaking your iPhone.]

Jailbreak iPhone 2G with OS 3.0

  1. This iPhone Jailbreak guide requires you to download the following: (1) RedSn0w for Windows, Mac or Linux; (2) the 3.0 firmware for iPhone 2G; and (3) the 3.9 and (4) 4.6 BootLoaders if you want to unlock your iPhone in addition to Jailbreaking. Save your downloads in a folder named “Jailbreak.”

  2. Launch RedSn0w and click “Browse.” Find the 3.0 firmware (the .ipsw file you just downloaded to your Jailbreak folder) and select it. Then click “Next” to restore your 2G iPhone to the 3.0 firmware.

  3. Choose whether to install Cydia, install Icy and/or unlock your iPhone. I chose to install Cydia (like an “App Store” for Jailbreak) and to unlock my iPhone 2G, which allows the iPhone to be used on non-approved carriers.
  4. If you chose to unlock your iPhone, RedSn0w will ask you to identify the bootloader files you downloaded in Step 1.

  5. Now turn off your iPhone (but leave it connected via USB), click “Next” and follow instructions.

    In under a minute, you will have a Jailbroken iPhone 2G.

  6. Let your iPhone reboot, open Cydia and download a bunch of cool apps and modifications that you could not otherwise download with a factory iPhone.

I have an old 2g iphone which is in Emergency call mode. I can’t seem to get it unlocked. I’m using windows 7 and don’t think I can get the old software to unlock it. Please help someone.

The instructions on this website are to be followed as mentioned to get it out of Emergency mode.
you can also contact us via our website if its too difficult for you.

You need to first connect your Apple logo stuck iPhone to iTunes.

And then hold the Home button and Power button at the same time for 10 seconds.

After 10 seconds, release the Power button. Do not release Home button, keep holding the Home button another 10+ seconds. You will see a message in iTunes that it has detected an iPhone in recovery mode.

Your iPhone is in DFU mode now. Click OK and click Restore button in iTunes.


I downloaded Everything, Got stuck on the .ispw download It Is a .zip Instead of a .ispw Stuck…
Broken link?

Hey if. I do this will this matlke it were I can use my prepaid data plan


my device is stuck at downloading jailbreak data


been through the process twice. everything looked ok and seemed to be working. then the phone sat there “downloading jailbreak data…” for about 5 minutes. rebooted and am back to only the emergency call state.

which is where i started. yay fun!


Mine is stuck saying “Downloading Jailbreak Data..” and everything else is completed. I hit finish on redsn0w because it said it was finished. What do I do?


Mine is also having the same trouble, has anyone found a solution or know the reason that causes this?


phone on eternal reboot loop is it bricked?

please tell me not!!!


Worked well. My 2G iPhone was initially on 1.1.4 (yes pretty old:) and by following another guide I upgraded to 3.1.3. Unfortunately this required an existing software of 3.1.2. After following instructions from a few other sites with no luck, I followed the instructions here and BINGO. Now unlocked and running 3.1.3.

oops. in reference to my last post, I meant I unplugged the iphone, then immediately plugged it back in (:

Thanks so much for clear instructions! Worked great on my iphone 2G. fyi the link to Redsn0w didn’t work for me; but easy enough to google up their page. Here’s a great spot to get firmware (including 3.0) : (? I was on a mac, but very similar…fyi at some point in the jailbreaking process Redsn0w got stuck saying “waiting for reboot”. I gave it an hour, then just unplugged the iphone. Redsn0w picked up fine after that and all went well.
Thanks again,





To those who got passed the jailbreaking but not unlocking you guys must of forgot to add the bootloader files so it just jailbroke it but never unlocked it



I tried the steps above, but my iPhone 2g i stuck on the apple logo and it restarts itself over and over again automatically. iTunes also don’t recognize my iPhone. What should I do? I already tried to disconnect the cable and connect it again very fast; it didn’t work.



were can i get the jail break for free or do i have to pay?…
