Hey guys I have a factory unlocked phone which I bought from china, and I also have it rooted, my friend wants me to to update to JB but I'm not sure if I have to unroot my phone to get the update and also if I unroot it will I loose my factory unlock? I'm using it in the United States right now. With carrier t-mobile.. I've also seen other posts about being slow after updating if it's international so what should I do?
