Data Squeeze at AT&T - Morning Business Memo

A big slowdown at A&T for the heaviest users of data. The number two wireless company is ending unlimited data plans.

AT&T has spent billions of dollars to build and maintain a new 4G network that can handle data traffic. The new limit applies to its 17 million customers.

Yelp's popular online reviews guide the hungry to the best restaurants, the thirsty to the friendliest bars and the flabby to the toughest personal trainers.

Yelp is pricing its stock IPO at $15 a share. That's more than expected. The offering values Yelp at $900 million.
