Looks like Sony is starting its Ice Cream Sandwich updates… if you’re in Sweden, Denmark, Iceland, Finland, or Norway. If you are, and you own an Xperia Arc S, Xperia Neo V, or Xperia Ray, get ready to start tasting some sweetness as the updates roll out over the next four to six weeks. These will NOT be over the air updates, so you will need a Mac or PC to install (which is pretty lame in my opinion).
Scandinavian Xperia users, hit the source link below to get started.
