Couldn't wait for the blue handset, so got one of the three white ones that 3 had today. Guess I was a very lucky boy because this is an incredible phone. Yes I've gone from S to S3 so always gonna be a huge step up, but wife has S2 and it's way better than even that.
Still messing about with it but if you have any doubts, forget them - just get one.
That's just a load of blather but will post later with something tangible once I've picked my jaw up. Awesome bit of kit and on 3's £34 all you can eat data plan, a proper bargain.
