Upgrade an old Jailbroken iPhone to firmware 3.0: Part 1

ohhhhh I love my iPhone. I have a 2G iPhone which I got just before 3G was about to get launched and I jail broke. It has been close to 18 months that I have been using this jail broken iPhone without any issues. I have been running it on 1.X firmware which it came with and never had any pressing need to upgrade it so far.

But today the lazy me have decide to either break it or upgrade it successfully to firmware 3.0. I am not sure what's going to be the outcome of this process but I am going to try it.

And I will keep updating this blog as and when I proceed further and keep documenting whatever issues I encounter for the benefit of all the other people who would like to try doing the same thing.

1. Upgrade to latest iTunes 8.2 : As a first step, I am going to install latest iTunes on my Win XP laptop. AFAIK, firmware 3.0 is supported by iTunes 8.2 only.

So, I was so far running on iTunes 8.1 and I have just kicked off the iTunes update process. The update process is downloading the update bit which is 83 MB in size. So, I guess it's going to take little time before I have iTunes 8.2 installed and then I will embark on my risky journey of 3.0 upgrade with a potential danger of loosing my beloved iPhone for always :(.

Ok, so after a few kinks, I could upgrade my iTunes to 8.2.0.23. I had few issue in upgrading iTunes. Just a note of advice: Close you iTunes after you have launched the iTune updater.

2. Backup you iPhone: take a backup of your current iPhone. In-case things go drastically wrong, you should not loose the many contacts and pics that you have in your iPhone.

Taking iPhone back is easy. Use the following steps to take a backup:
1. Connect you iPhone to laptop with iTunes running.
2. Once iTunes detects your iPhone, right click on iPhone appearing on left hand panel in iTunes under "Devices" category. You will see an option to backup your iPhone.

3. Upgrade to firmware version 3.0

Let's start the risky journey. While you iPhone is connected to iTunes, you would notice that iTunes in the "summary" tab have the details of what's the current firmware version that your iPhone is running and what is latest one available.


My iPhone is currently running 1.1.4 firmware ( how outdated I am :( ). I am going to click on the "Update" button that you see in the image to start the upgrade to 3.0 process ( and god knows what will happen to my iPhone after this, Let me have a last look at it ;) )

1 ....2........3.......... and I have clicked on the "Update" button

I am not sure, how much time this download and install process is going to take. Let's see, it's 1208PM local time that I have kicked in this process. I am hoping that at the end of it, I should have an iPhone running on firmware 3.0 and locked all over again which then I will have to jail break again.

And It the download got over at 1.30PM local time.
