Upgrading Unlocked Apple iPhone from 1.1.1 to 1.1.3

Just last week, George Hotz or “geohot” as he is known did some amazing work on unlocking the iPhone for OTB 1.1.2 and 1.1.3 iPhones as well as unlocking upgraded iPhones. Since I’m using my iPhone on Vodafone in India, I didn’t want to upgrade from 1.1.1 to 1.1.2 as the unlock for 1.1.2 wasn’t an “official” dev release. But now, as the developer community has managed to unlock the iPhone under 1.1.3, it seemed like the right time to upgrade – though with a little bit of pain.

There are plenty of sites that explain how to upgrade a 1.0.2 or 1.1.1 iPhone to 1.1.3 and unlock it. I won’t go into writing a full post on how to do it. What I will do, however, is explain some of the “gotchas” during the upgrade process. Your mileage may vary depending on the method you use to upgrade. I primarily used the instructions at How to jailbreak 1.1.2 or 1.1.3.

I started with an unlocked 1.1.1 iPhone that was upgraded from a 1.0.2 iPhone. I had revirginzed the 1.0.2 phone and upgraded to 1.1.1 and unlocked using anySIM 1.1.1.

The first thing I did was to sync my iPhone to my MacMini and then do a complete restore my 1.1.1 iPhone to 1.1.1, thus wiping out all the garbage that I had accumulated in the last few months. Now, once the phone was restored, the unlock was still active but I had to jailbreak the phone as described in the instructions above.

After jailbreaking the iPhone, I installed the OktoPrep package from Installer.app. I then started downloading the 1.1.2 jailbreaking archive. Now it is critical that you do an UPGRADE from iTunes to 1.1.2 as described on Unlock.no. If you do a restore by mistake, you will have to restore back to 1.1.1, jailbreak it, install OktoPrep again, then, finally, UPGRADE to 1.1.2. Following the directions, made it very easy to jailbreak and use my 1.1.2 iPhone. I unlocked it using anySim 1.1.2u and the installed iWorld from the “Tweaks 1.1.2” section of Installer.app.

Now, upgrading to 1.1.3 using the instructions at Unlock.no were great, BUT, I found that doing a Restore didn’t allow my iPhone to reboot no matter what I tried. Hence, make sure when you’re running the “Official 1.1.3 Upgrader” that you tap “Upgrade” and not “Restore”. If you follow those directions an repeatedly “Update” from 1.1.1 to 1.1.2 and then 1.1.2 to 1.1.3, you should be able to start your iPhone running 1.1.3 already unlocked.

Since upgrading to 1.1.3, an easier 1.1.3 unlock has also been made available but I have not tried it.
