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.
