James Moore: 4G dials the right numbers at Carphone Warehouse

Outlook It may be expensive, but consumers are buying into 4G mobile phones.

Happy days for Carphone Warehouse then, which is enjoying life as a warm, if not hot, stock again thanks to the latter's impact on its sales.

Free of its US entanglement, life is just dandy right now. Just don't mention Virgin Mobile France. America's "oldest ally" as secretary of state John Kerry described it, is still causing a few problems. So may the desire of mobile networks to bypass it and sell direct.

But for now Carphone is enjoying another set of salad days. Even the retro name seems kind of cute, if increasingly illogical in an era of data transmission, tablet computing and clouds. But it would be a bit mean to rain on Carphone's parade just now, wouldn't it.
