Boost mobile and 4G
Sprint's policy, ever since acquiring both carriers, has been to feed them the sloppy seconds from its table. What is Boost's best phone? Now, compare it to Sprint's lineup.
In short, when will Boost get 4g? As soon as 4g becomes so common for Sprint thast they feel they can afford to send a cheaper phone down the prepaid line. And even then, it'll go to Virgin Mobile first before Boost.
