Buoyed by soft promotions around the latest iPhone, Verizon Communications Inc. boosted revenue and its subscriber rolls in the third quarter, a sign the carrier's return to unlimited data plans earlier this year has stanched customer defections. Verizon added 603,000 monthly postpaid connections in the quarter, nearly double what Wall Street expected. The company had 115.3 million total wireless retail connections, up from 113.7 million the same quarter last year and 114.5 million in the second quarter. Verizon shares rose 2.2% to $49.73 in midday trading Thursday but are down about 7% on the year.
