HTC and Sprint have sent out invitations for an April 4th event in NYC to announce their "latest collaboration." We don't have much more info here, but hopefully we'll learn some more about the mysterious HTC One X variant for Sprint, which has been called many things from the Jewel to the Jet to the EVO HD LTE. We previously reported a rumored June 10th launch date
for the phone, and an early April announcement seems plausible. We'll of course keep you updated as we find out more!
