Cell phoning from home pits WiFi against femtocells

"What the eff is a femtocell?" you might be asking yourself. Short answer: another mystery box to add to your home network, but this one let's you make mobile phone calls over your broadband Internet connection.

"Couldn't I do the same thing with a WiFi-enabled mobile phone?" Why, yes, yes you could. If you can find one.
