I saw a video where they rooted the s3 up to 1.8ghz would it be possible to push it to 2ghz? Also does the carrier matter? I'm eyeing virgin mobiles 4g lte, I kinda was a gsm version because you never know where you're gonna be tomorrow. I dont hink I'll notice a major difference in lte vs 3g. Also if rooted and I buy a prepaid phone will I be able to unlock to a different carrier say att?
