Verizon today reported slower growth than usual in a sign that Android's effect was muted at the carrier. It added a modest 997,000 cellphone customers during the summer compared to AT&T's 2.6 million and was enough to put the two carriers' total bases nearly even, with Verizon just holding a lead at 93.2 million phone users versus AT&T's 92.8 million. Verizon's main advantage was lower turnover of old subscription customers for new, at 1.07 percent.
