AT&T subscribers who own the HTC One X should get ready for a dose of Android 4.2.2.

In a message tweeted late Monday, an HTC executive said that AT&T has approved Android 4.2.2 for the HTC One X and aims to launch the over-the-air update on Wednesday.

The regular HTC One is on the path toward receiving Android 4.4.2 KitKat. On Monday, HTC's Software Updates page showed its flagship phone as being certified by all four major US carriers -- AT&T, Sprint, T-Mobile, and Verizon. The update has reportedly started rolling out for European users of the international version of the HTC One, according to AndroidCentral.
