How much is it in a phone store?

Depends on the store. But these kind of topics are not really allowed here...

i thought you werent allowed to talk about it if you werent doing legitimatly?

I just wanted to know how much Carphone Warehouse say, would charge me.

Then, why not simply ask CPW directly?

I should think a direct answer from whomever sells/provides the service is better than an indirect one.

And it would be faster too, I suppose (the same time it took you to write your original question, you could've used to call CPW and get the answer). Now a couple of hours have passed, already, and you still have no answer. ;)

im in no rush.
