its a very useful tool, 2 me anyways. 3.3 is latest version. i installed on mine. as far as carrier specific settings, i didnt think i seen anything like that, or that it even matters. as far as safe, it depends on what you do. if you mess w/ settings you dont know bout then you might screw something up but if it comes down 2 it, its nothing a hard reset cant fix.
