So we know the iPhone has been slumming it and selling itself on Walmart shelves in the US for a while now, but it's retained a somewhat more dignified cachet over here in Europe. Until today, that is. Just "in time for Christmas," British retailer Tesco will make it possible for you to buy your socks, no-frills groceries, and shiny smartphone all in the same place. You'll still be riding O2's network, thanks to the Tesco Mobile service, but the department store chain is likely to price its contracts more aggressively, as it already has a £30 per month plan that includes unlimited calls, texts, and web surfing. Maybe there's something to this whole "competition" thing after all then, eh?
