Revenue from home-phone lines, AT&T's traditional business, is declining as more customers move to mobile phones and digital service. Sales and net income declined in 2009 amid the global economic crisis.

The company rebounded in 2010, benefiting from surging demand for smartphones, including Apple Inc.'s iPhone. Revenue grew 1.4 percent to $124.3 billion last year.

AT&T fell 21 cents to $27.92 in New York Stock Exchange composite trading Friday, and has declined 5% this year.
