The Japanese version phones (Xperia acro HD and Xperia NX) have IPX5/IPX7 certification.
Waterproofing equivalent to IPX5/IPX7  means you can use the phone and camera without worrying about unexpected rain showers. This is a useful feature in today's business climate.
IPX5 is the grade at which a phone continues to function when directly subjected to 12.5 L of water per minute from all directions using a 6.3 mm inside diameter nozzle at a distance of approximately 3m for at least 3 minutes.
IPX7 is the grade at which a phone continues to function and no water gets inside when it is immersed in a tank filled with still tap water to a depth of 1m at room temperature and left at the bottom of the tank for approximately 30 minutes.
What about the international version of Xperia S?

indeed its really enfuriating, that a country will get waterproof phones but not the rest, but I rather have Gorilla Glass or Gorilla Glass 2 or Dragon Trail than waterproof
