If Im mistaken if you go to the leaked rom youll never be able to obtain root again, thats the theory so Im saying dont go for it.. Im not sure if they have roms for the moment cause when I had it a month and a half ago they didnt, but thats when they had just gotten root so theres a few most likely, go look on the samsunt moment forums from various sites
but try not to go with the leaked 2.1 unless theres root in there
