While HTC just officially announced the One X at Mobile World Congress and AT&T shotgunned exclusive rights in the U.S. to the beast for its LTE network (albeit packing a Krait chip instead of the Tegra 3), there's now a rumor floating around that Sprint could be getting a device similar to the One X, codenamed the Jewel.

Details on the Jewel are scarce right now, but rumor has it that the device is packing a large HD display (similar to the One X) and should be one of the flagship devices on Sprint's upcoming LTE network. Pocketnow, who was originally tipped about this device, goes as far as to speculate that this device could be released as the "EVO LTE" - an idea that makes perfect sense considering the EVO 4G helped usher in Sprint's WiMax network.

Of course, this is all just a mix of speculation and rumor for the time being, so there's no estimated launch window at this point. Perhaps we'll see more information arise at the CTIA conference in May.
