While Android users are getting so familiar with custom ROMs like CyanogenMod (CM7, CM9) and many other creative custom ROMs, iOS users may have to be patient until this day. Finally, a well-known iOS hacker has demoed a nice action of -probably- world’s first custom firmware ever created. This third-party firmware for iOS devices seems to work pretty sleek.
The main usage of this custom iPhone’s firmware is to bring some iOS 5 features on old iDevices running iOS 4.x.x which in the video below demoed to run on iOS 4.2.1.
However, this project is still in Alpha beta version but we may expect its final public release soon.
Some known leaked features of this custom iOS firmware: custom backgrounds (wallpapers), the semi transparent dock, new system sounds, new icons from iOS 5, multitasking, tap-to-focus camera, a special version of iCloud that uses DropBox and much more.
I don’t really sure whether you have to try it or not. Just find your own reasons of why you have to try and run this custom iOS on your iPhone / iPod Touch. Make sure you also check out its Facebook page [link] for quick update.
