iPhone OS 4 Being Ported to Original iPhone


When iPhone OS 4 was announced, and we got to hear some of the new features coming, there was excitement. then disapointment, as we learned only the iPhone 3GS and the newer, unreleased iPhones would get all the features. The jailbreak community quickly learned that some of the missing features could be added to the iPhone 3G, by manipulating  a plist file to enable them. With no OS 4 firmware being made for the original iPhone hardware, it’s not as simple as that to get the OS 4 on the aging device.

A European hacking team calling themselves “Fittingstorm”, claim to be working on building a custom iPhone OS 4 for the original iPhone. Apparently, they have had some crude success, but are having some trouble with connectivity for phone, data, and wifi.

Here’s what their blog has to say about the project:

“…we are going to a new challenge Apple’s smartphone, take the next firmware 4.0 out in June on the old version of the smartphone which Apple decided not to publish it. To do this we studied the very advent of the jailbreak and the people who have worked, and in particular we have focused on PwangeTool tool that lets you insert a custom firmware jailbreak devices, and from there gave rise to our idea. Of course what we’re trying to do is something much more complex because there is no official firmware 4.0 for iphone 2g, and our task will be to rewrite those parts of code to adapt it to the device. A project long enough but after just one week after the beta release has led to exciting results, we have created a tool that looks a lot like PwangeTool and loading a custom firmware that 3 of us are rewriting part, starting from Beta 1. The result was deich after a day of hard work that was performed on 4.0 firmware 2g device but with many problems, in fact almost nothing worked. Since then many things have improved, we refer to the next page for details.”

So, is this real, or just another bunch of kids pulling our leg? It’s hard to say, until we see some proof of concept, at the least. They have not released anything, other then what they say is their progress, on their blog. Even if they do get this to work, will it be usable? I know iPhone OS 3 is pretty laggy on the original iPhone, so I can only imagine it being even worse with the new OS. I’m sure this is why Apple has decided not to release iPhone OS 4 for the iPhone “EDGE”.

Unlike the original iPhone, I am fully compatible with OS 4! Follow me on Twitter: @rorypiper


  • If this is indeed true, a tonne of iPhone 3G owners will be very happy. It will be interesting to see how well multitasking really works on the 3G if this project comes to fruition!

    i tend to rarely have more than 20mb of free ram at any given time (with no apps running in the foreground),. i doubt it'll be decent….cool feature to have hope it doesn't slow things down.

    what i'd liekt o see though is the model and imei of that phone in the screenshot to see if it's legitly running 4.0 😛

    I bet it will be so slow that it is totally not useable on 2G or 3G
    Programs like Navigon barely work on the 3G

    I have the 3G and multitasking is working very well with it. I used to have intelliscreen and backgrounder and it was slow. After removing Intelliscreen, replacing it with Lock Calendar, and having backgrounder and pro switcher, the 3G is still a very usable and responsive device.

    I'm currently testing 4.0 and the Backgrounding ability is nice (3GS) explained that it lays as a package when slipped in to the background, cutting resources n CPU usage. That's how they solved the battery issue they talked about back when people screamed for multitasking last year at the 3.0 release. If this is as Jobs say it is, I don't see why the 3G/2G wouldn't get multitasking. If it cuts resources while in the background I fail to see the issue, but then again there might be more i'm missing here. Those are just my thoughts anyways.

    That “photo” is fake. Looks like a fairly well done 3D render to me.
