I have a Samsung Galaxy tablet model SCH-I800. Its a verizon tablet that I opted not to renew the contract on. I only use it on my Home Network. I am getting tired of all of the Verizon stuff on it and would like to streamline it to be used only for Web surfing and email. I guess my questions are: 1.Can I get a faster OS or make this thing faster some other way? 2.Is it even worth the trouble?
