Hi all. I want to keep this short and simple. I have the I9020A with 4.1.2, and a couple of days to spare. My phone is running OK and I am happy, but if I could improve the performance or experience it would only be better. How long does it take to root and install a new ROM (or so they call it) like CM 10.1, for a beginner like me? And, very briefly in one sentence, what are the main benefits from rooting and gains I could see from a ROM like CM 10.1?
