Get the optimus m, you won't be able to get LTE with with optimus bit you will have access to the android market, on the samsung craft you won't get as wide of a selection of app, or any at all (am not sure if there is some way of getting app onto the craft from any source other than metros online store). The 4G experience and the samsung craft seems to be disappointing (based on vids I've seen on YouTube). I think the 4G would be slightly faster than the 1x u currently get on metro,or about 3G but definitely not 4G. And besides the craft is not a smartphone dispite it's smartphone features. With the optimus m u get android along with the android market which is the main reason why u should consider it over the craft.
