You know what they say – better late than never. If that is the case, Sprint has certainly stayed true to this particular saying, by rolling out BlackBerry 10.2.1 for their subscribers. Verizon as well as T-Mobile subscribers already dished out this particular mobile operating system update last month. Well, at least Sprint’s customers have finally played catch up in this particular matter, and do bear in mind that the only BlackBerry 10 model that is sold by the carrier happens to be the BlackBerry Q10.
