WIFI or 3G

WIFI being used on smart phones more than 3G. This should surprise no one - but most of Mobile companies have now moved over to limited data plans (500mb or 1 GB a month - woooo, how generous they are. That's about 45 minutes worth of an iplayer program) and are probably wondering why so few people are taking them up on it. They hard sell all these whizz-bang internet connected smart phones but want to gouge you for using them.
