Verizon smartphone owners may ultimately use more data than their supposedly more aggressive iPhone-using counterparts at AT&T, Validas discovered. Despite stereotypes, those with Droids and other Verizon devices use about 25 percent more 3G data on average, chewing about 428MB per month where an iPhone owner uses 338MB. Very frequent users are also much more common: 11 percent of Verizon users consume between 500MB and 1GB of data where half as many (5.6 percent) iPhone users do the same.
