The Android modding community has already taken advantage of the release of the Ice Cream Sandwich source code by delivering unofficial ports for the Samsung Galaxy S II and the LG Optimus 3D. Now we can add the original Samsung Galaxy S to the list.
The ported ROM works only with the international version of Samsung's phone — owners of US variants like the Captivate and Vibrant will have to wait — and is clearly still in the early stages. Calling, SMS, and Wi-Fi are all functional, but other basics like 3G data, the camera, and GPS are still a no-go. Given the dedication of Android developers, it's no doubt just a matter of time before these obstacles are hurdled, and with Samsung silent on the status of an official ICS update, this may be the only option for Galaxy S lovers. If the port sounds like it might be for you, check out the source link below for instructions on how to upgrade.
