I recently upgraded my unlocked 1.0.2 version iPhone to 1.1.3 using Zibri’s Ziphone .

I tried looking for a guide for the same on the Internet. However all I got were comments from experts about the procedure and certain comments from people who had done this.

Here is what I did to upgrade. Note that these steps are meant for Windows users having 1.0.2 iPhone unlocked using the iUnlock method (prior to anySim ):

DISCLAIMER: The following steps worked fine for my iPhone. Try them at your own risk. I cannot guarantee that the process will always be successful.

1. Back up your contacts and phone’s content in iTunes.
2. Set auto lock to "Never" in Settings -> General -> Auto Lock
3. Add "http://i.unlock.no" to Installer sources and refresh
4. Go to Unlocking Tools in Installer and install Virginizer. This step will take about 15 minutes. Your phone will not recognize your Sim after this step.
5. Download 1.1.3 firmware file from the link on http://iphone.unlock.no/#restore-firmware-files
6. Connect your iPhone to the computer & start iTunes.  Once the phone is detected by iTunes, hold "Shift" key and click on the Restore button on the Summary page in iTunes. Select the file you just downloaded. iTunes will start restoring (read upgrading ) your iPhone to 1.1.3 firmware. This process will again take around 15 minutes to complete. Close iTunes after this step.
7. Download Ziphone from http://www.downloadziphone.org/
8. Install .Net Framework 2.0
9. Start Ziphone & click on "Do it All" button. It will detect the phone and start the activate, jailbreak & unlock process. This will take approx. 5 minutes to complete. Close Ziphone after this step. The phone is now upgraded to 1.1.3 and is unlocked. It will have Installer installed. You can test by making a call.
10. Once you are done, start iTunes. Set up the phone using the backup you took in step 1.

I had a small problem with wifi after this process. I used ad-hoc wifi at my home to connect to the internet from the iPhone. However, after this process, the iPhone wasn’t able to keep the ad-hoc connection. I reached out to the folks at the official Ziphone channel (#ziphone) on irc.ziphone.org and they helped me out. The solution is to connect the iPhone to a proper router based wifi hotspot. Once it is connected to the hotspot, it will be able to connect to ad-hoc networks as well. I was anyways looking for an excuse to get a wifi router. So I utilized this opportunity. The iPhone works perfectly fine with the router wifi.

In case you have any queries regarding the unlock process or Ziphone, I guess its best to reach out to the experts on the IRC channel. I do not have much expertise in this. I am posting the above steps to help out people looking for a guide.

Thanks to Zibri, Geohot & iphone.unlock team for coming with this.

Update: Thanks to Mr. Farooqi for the discussion. You can use the above process to upgrade to 1.1.4 as well. Just download the 1.1.4 firmware file in step 5 above. Rest of the steps remain the same. Enjoy!
