And how much will it cost?

i think i paid about £7. there was a shop in the mall that did it.
(wow that was so not helpful. sorry)

Thanks purplemonkey!

anyone on where I can do it? I'm in Northampton.

look on the website for your provider and they should tell you - I've seen it on my Virgin Mobile site.

Usually a market stall will do this for about a fiver.
