Sprint and HTC have just sent out invites to an event to take place in New York City on April 4th. Sprint CEO Dan Hesse and HTC president Jason Mackenzie will be on hand to show off the “latest collaboration” between the two mobile players. The invite provides little to speculate over with no clues or hints seemingly hidden within (no giveaways in the filename, either). Our minds immediately jump to rumors of Sprint launching their own version of the HTC One X, potentially under the name HTC Jet, in June. Of course, Phandroid will be on hand for whatever is unveiled at the day’s event. Stay tuned.
