The Jet was announced on April 4th as the HTC EVO 4G LTE. Pre-orders for it start on May 7th.
There was supposedly a conference about the HTC Jet... Sprint's version of the One, on April 4th 2012, but I can't find any info for it. All threads and external websites I can find end before the 4th. Does anyone know if the Jet is still coming to Sprint on June 10th?
The Sprint variation of the One X is being announced tomorrow, however it is the dual-core version of the phone which is a good thing considering the dual-core S4 outperforms and uses less battery than the quad-core Tegra 3 version. I'm not even sure why they bothered making the Tegra 3 version since it's not as good. Perhaps the chips cost less and it doesn't make since to pay more for areas that don't have LTE.
Sprint will have a release party this coming week with HTC in NY on the 5th of April. So I would look for it to be announced then, I see the Jet being announced along with some other sweet ones..
Nothing has been officially announced yet unfortunately. As always though news and updates will be posted to http://newsroom.sprint.com/news/
