The HTC One X was renamed to the HTC One XT for Chinese launch and the HTC One X to the HTC One J. Letter J perhaps stands for Japan, though it doesn’t mean anything, in general.
As to the HTC One XT, it looks like the original One X and is packed with the same features. The only difference lies in the radios — the One XT sports a TD-SCDMA radio to support China Mobile’s 3G network, while the original One X supports CDMA and GSM bands. Moreover, it comes with an Nvidia Tegra 3 processor with four cores thanks to the replaced radio. The HTC One XT is already available in China Mobile’s stores at 5,688 yuan ($899 or €707), and this is a good chance for Taiwanese HTC to expand its market share in the market because this carrier is the world’s largest carrier with 650 million subscribers.
The HTC One J is the alerted model of the One S — it sports different features and design. The phone will be launched with a 1.5 GHz dual-core Qualcomm Snapdragon S4 processor, an 8 MP camera with many software enhancements, Beats Audio, mobile TV, will have an IR port and run Android 4.0 Ice Cream Sandwich. The launch date is set on May 25. It will be exclusive for the Japanese second largest carrier, KDDI. And lastly, the HTC One J will support WiMAX network.
