Do all HTC One X's use the same screen? I'm going to replace the screen on my HTC One X, but I'm nervous of buying the wrong LCD assembly (I did that with a version of the iPhone 4 before).

Somehow no one seems to have an answer for this - do all versions of the HTC One X use the same screen assembly? My serial starts with HT23, and not the GS23 that so many eBay advertisers have in their description.
Yes they are the same.  The one x and x+ use identical display and digitizer.  Buy the assembly the digitizer is adhered tightly to the lcd.
