have u chosen yet? haha if not i'd say silver. only because almost everyphone thats being released has a black version. why not go back to silver? =) its really not that bad... =P
black definately looks better, but I once had a black phone and that scratched pretty easily. So maybe silver is the better choice.
i think the black looks really cool with that orange. sony ericsson is coming out with really nice phones this days..
