Waiting to see how the blue looks in person, the white isnt half bad but already own a white s2 so would be either blue/black.
If you have the time, then pop down to Westfield in Shepherds Bush, they have both the white and blue models there on display...i dont know how long they will be there for though.
Personally i prefer the blue one over the white, given my reasons over in teh SGS3 thread already running but the white just didnt do anything for me whereas the blue one i saw and held was a lot more nicer in real life than on the pics.
Thanks man, went to strat west field and rep there said there wasnt the blue anywhere really xD.
