As mentiond by Ayuclack, I would like to second him in this regard.You might flash your cell innumerable number of times , if you know what you are doing (In this context I do apprehend that you know how to flash your mobile , using J.A>F and Pkey emulator and the subsequent procedure) . Fo CFWs you can look upto sites like dailymobile.se , Symbiantalk and pnht.pl . They do have a whole lot of CFWs ,and also whilst flashing, do take not about your RM version as well. Happy flashing, cheers \m/
