Cisco recently estimated the amount of mobile data traffic for the year exceeded the entire Internet’s in 2000. That should only accelerate in 2011, as more consumers trade in so-called feature phones for iPhones and advanced phones running Google’s Android operating system. By some estimates, the number of smartphone users will surpass feature phone users this year.
