Before I screw up my phone I have a couple of questions. I have a SGH-I537 running 4.2.2 MF3. First off I don't have AT&T anymore. I have H2O wireless. Wanted to know if that made a difference first off. If it does is there still a way for me to root my phone? I would also like to know if there is a way for me to update to kitkat? Thank you, this is the best site.
