got it new......did you buy it new or 2nd hand?
i purchased mine and it came unlocked and whatever sim i put in just worked.
is it coming up with error msg's? like no network? or enter code?
when going in to the calls menu it comes up saying network or sim error..... and when using orange sim it just says Emergency calls only
im sending this one back and i've just ordered another one, which i will receive by the 14th.
