first and foremost,while id like to take credit for scotts roms,i cannot. he is scott scrossler,im just scotty85. as for your other questions,ive moved this to the forum so that the others can share their rom experiences with you. .10 is not the newest leak,there was .3.14.605.12,and then the "world phone" update to 4.03.605.1. there are stock rooted versions for both from various folks on xda. the world phone rom should work with your current firmware,except for the actual world phone part,wich supposedly requires the new radio to go with it. if you wish to get all the way up to the world phone rom and firmware,the process can differ slightly if youre s-on or s-off.
