Samsung SGH-i600

do these things ready to slip my sim card in them???

Can u get a video player on it ?

yeah core player tcpmp and i think windows media is alreday on it. i use core and tcpmp on my moto q and te blackjack is practically identical bcause they run wm5 and i think wm6

can you go on myspace/facebook on this? or watch youtube videos??

for youtube you need a video player (haven't tried yet), you can't' use directly explorer. For navigation in facebook/myspace...depends. The typical myspace page (lots of ehm...stuff) is difficult to reender on a little screen. Facebook have a mobile interface.

what mode do you have your home screen set on

This is a home screen made only for i600s unbranded, i think is called Samsung Carousel

i600 have wifi and hsdpa in plus

whats the difference between the american version?

I don't know, but wm5 phone edition is pretty limited, i.e. you can't set a fixed ip to your connection from the gui, only dhcp... i've tried to modify some setting in the regestry with no luck
