A Russian hacker named ZoRn has developed what he is calling ROMpatcher. In a nutshell, ROMpatcher does exactly what the name dictates; it allows you to quickly and relatively easily apply patches to the ROM on S60 devices. For the time being there are only a few patches available which essentially just a few tasks that already existed (access to protected directories, circumvent certificate check) but now that the flood gates are open, expect the water to start roaring soon enough.
In short, ROMPatcher makes the S60 platform truly and finally open to anything, this is the amazing piece of code, application allowing patching the ROM on the very easy and very secure way and our imagination is the only limit when it comes to the number of uses for it.
There is no real danger for the end user, it is the very well known technique that maps ROM into RAM and then modifies it, of course, it has some downsides because patch is not a permanent and restart will clean all changes made by the little application.
Of course, it is always highly suggestible to back up phone as precaution measure and than in worst possible scenario it will be enough to format the phone and restore back up.
