Sprint, Motorola have something up their sleeves on June 9The invitation for a joint Sprint/Moto press event in New York just popped into my inbox, and all we know for sure is that the CEOs of Sprint and Motorola Mobility (Dan Hesse and Sanjay Jha) will be on-hand to show off the “latest collaborations” of the two companies. Could we be talking a new Android smartphone? A tablet? (Update: A Sprint-branded version of the Motorola Xoom?) Something else entirely? Looks like we’ll find out come June 9; stay tuned.
