Verizon today provided a mild shock to the cellular industry by reporting relatively disappointing results for the early part of 2010. Although still taking advantage of phones like the Motorola Droid, its subscriber growth slowed down to 1.5 million new cellphone users in the winter and was noticeably slower than AT&T's 1.9 million additions over the same timeframe. Its net profit also plunged from $1.6 billion a year ago to $400 million today.
