The first site you linked is crap. All they did is get articles of the S2 and change that term for R.
However, I am cooperating with another person to build an insecure kernel for this device (well, to be fair, he is doing all of the work. I am only providing the info that he needs of the phone and trying out his theories). The thing is that we hope that in a near future we will be able to root the Galaxy R with the file we are making and an app called S2 Root, which allready supports our phone.
