One X or Galaxy S III

AT&T apparently isn't calling the One X the "One XL" anymore. Internal documents are calling it the One X.

HTC's official name is OneXL, with the L standing for LTE. Whether or not AT&T calls it just OneX is irrelevant, because it is a OneXL.

The One X is the name for AT&T's version. The One XL is the name of the unlocked international version with the S4 and LTE built-in.
