i just bought a Fascinate today that was rooted. it's on 2.2.2, and as far as i can tell there is no custom rom on it. how do i go about unrooting, and if i do, will i be able to root again? i want a completely fresh start since i don't know what this guy has done on the phone. also, the battery cover is pretty messed up. it still works but it has a lot of scratches. anyone know a good battery cover under $10 including shipping?
