Updating the iPhone 3G to the new 3.0 firmware

I recently updated my iPhone 3G to the new 3.0 firmware.

The process went very smoothly involving the following steps.

  1. I synced my iPhone to iTunes in order to preserve my contacts and App Store installed apps;
  2. I updated the iPhone to the 3.0 firmware using iTunes;
  3. At this point my iPhone got locked and I had to activate it using an Orange SIM card (the Jailbreak process should fix this step for you, but it didn’t work for me; it’s a safe bet to have an appropriate SIM card around);
  4. Jailbreak using PwnageTool 3.0 for Mac; first I tried using expert mode and toying around with the settings… that didn’t seem to work and iTunes gave me the infamous 1600 error; I restarted the PwnageTool process using the default settings, putting my iPhone into DFU mode and uploading the custom firmware through iTunes;
  5. Bingo, my iPhone was now Jailbroken but not unlocked; I added the repo666.ultrasn0w.com into Cydia, searched for and installed UltraSn0w and rebooted the iPhone;
  6. I now had a running jailbroken and unlocked 3.0 iPhone 3G !

You can see the official iPhone 3G and UltraSn0w tutorial on iPhone Dev Team’s blog.

    Hello! I bought a jailbroken and unlocked iphone 3G to a friend, with 3.0 firmware. I was having problems trying to install new applications (they needed the 3.1 firmware) so this morning I decided to upgrade. I used the Pwnage tool with no problem, but now I need to unlock and I don’t manage. I can’t enter Cydia because my phone is blocked. The sim is blocked and I’m only allowed emergency calls. On the screen, I have the USB cable going to Itunes icon. What can I do? Thank you very much

    Hello!
    At this point you will probably need a SIM from the network the iPhone is locked to.

    With that SIM you will be able to activate the iPhone and then jailbreak/unlock it.
