asda mobiles

Hi,

I just visited the asda web site and they have dozens of phones for
sale. When did they appear? Last time I looked, they only had a
limited choice. I've just ordered a handset from the Nokia shop and
it's £20 more, I wonder if I can cancel the order ;(

They also appear to be unlocked:
