just trying to get all the facts rite before i try flashing it as i don't wana frell it up lol

any one tried one of these ? and if so what software works with it and which firmware is best to use
i know there are a lot of questions but i have searched thoroughley for the answers and just keep running in to a brick wall every one i ask seems to contradict the person previousley so i thought the best place i'd get honnest unbiast advised would be the guys and girls here.
