Sony Xperia V goes to Japan as Xperia AX
The Sony Xperia GX, Japan's version of the Xperia TX, hit the shelves before the world-wide version of the phone was even official. Now, the positions are somewhat reversed - Sony just announced the Xperia AX, the Japanese version of the Xperia V (which isn't on sale yet, so it's not quite the same).
Anyway, Sony Xperia AX is pretty much an exact replica of the V - IP57 certification, 4.3" HD Reality display, 13MP camera, LTE connectivity and dual-core Krait processor. It will come with Sony' Walkman app, ClearAudio+ and media apps.
The rest is the same - really, Sony's blog even used a picture of the Xperia V (including the note below it), instead of an actual Xperia AX image.
The phone will launch running Android 4.0.4 Ice Cream Sandwich by the end of the year (so it will probably launch around the same time as the Xperia V does).
