Original iPhones (metal back, silver color, referred to as 2G iPhone) are blessed with a fully unlockable baseband 04.05.04_G. It entitles the iPhone 2G to be easily hackable. So lets get the ball rolling and get to the latest 3.1.3 firmware with a full unlock, jailbreak and activation in place!

Step by Step :

Download redsn0w 0.9.3 from downloads section and extract them to your Desktop [Both Mac and Windows versions of redsn0w are available there]

Connect your iPhone 2G to your PC/Mac and launch iTunes [Update iTunes to the latest version]

Update to 3.1.3 firmware directly from iTunes itself [Just click the update button in iTunes]

Meanwhile, download 3.1.2 Stock iPhone firmware and save it on the Desktop [Make sure it is .ipsw extension and not .zip]

Once the update is done, launch redsn0w 0.9.3 and click on browse button and browse to the 3.1.2 firmware that you just downloaded [Saved on Desktop] and click Next as shown. Follow the screenshots and proceed accordingly [Make sure Unlock and Cydia are checked]

Download the bootloader files for iPhone 2G. Extract the downloaded files 39.bin and 46.bin to the desktop.

When you are prompted for the bootloader files 39.bin and 46.bin in redsn0w , browse to the respective files saved on the desktop and click Next.

Now make sure your iPhone is connected to your PC/Mac and turn it off [Hold the power and slide to power off] and click Next.

Now follow the on screen instructions carefully, it is ok to miss those on the first try. Click back and try again [The 3 steps should as prompted should be done in the time shown on redsn0w].

Now let redsn0w do its thing! You will see some images on the iPhone which means it is jailbreaking, unlocking and activating your iPhone 2G! Wait till you see the homescreen, in other words leave the iPhone alone for few minutes.

Enjoy your jailbroken, Unlocked iPhone!

  4. I tried activating my 1st Gen iPhone using the iTunes software, legit with AT&T… I must have tried about 100 different times with 4 different versions of iTunes. No matter what, my iPhone would not unbrick and activate. This worked great. The only problem I encountered is that Internet Explorer kept downloading the ispw file as a zip. I had to install Firefox and download the ispw file from there. Thanks again so much!

  6. excellent, thanks for all the help – one jailbroken iphone 2g 🙂 One problem I had was that explorer kept ownloading the ipsw as zip files and I couldn't extract the data, so I installed firefox anad the files downloaded straight away

  12. A millions of thank you! The last time i unlocked and jailbreak my iphone 2g was long way back to year 2008 using Ziphone. But the Apps tool being outdated and some apps i've download eventually can not be used.

    Now at last i can have Cydia in my iphone. Very glad!

    Thanks!!

  13. Oh my word – this actually worked – I love you! Having spent 9 hours yesterday trying to get my phone unlocked, thsis worked in about 10 minutes – you sir, are a genius!

    2. same here…i spent all night trying to get it to work. apparently i needed to download the correct version of Redsn0w AND download the right firmware.

      i have an iphone 2g with 3.1.3 on it already.
      i uploaded the iphone firmware 3.1.2 with Redsnow, version 9.3 (NOT 9.5***) 9.5 doesn't recognize the 3.1.2 firmware file.
      i uploaded the two .bin files (BL-39 and BL-46)
      i selected 'unlock' (i didn't select install cydia because mine was already jailbroken-i jailbroke it a couple hours ago)
      then that was it! finally it works with

    1. Remember to have a sim-card plugged in….. I tried without a sim first, and it didn`t work. Tried again with the sim-card and it worked like a charm 🙂

    2. I did try twice and it didn't work, but I tried 3rd time, it worked on my phone. You need to do exactly what it instructed in order to get result. Especially the 1st step. You hold on the power button if you see the apple icon appears then hold on home button if you see power on it is is working. Just follow the 3rd step. If on the 2nd step, you see your phone is black, it won't work. You must start again by pulling out the USB cable and re-plug it in and make sure your phone power is off. Good luck.
