You can change country or region you just have to edit your profile in Itunes using your desktop or laptop pc, sa mobile i havent tried, done this kasi maaga nirelease ung Plants vs Zombies 2 and australia and new zealand ang unang nakakuha so ung i logged in on itunes edit my profile just search google for the country and zip code.. usually country, state and zip code lang inedit ko and un accepted naman nya.. kaya un palipat lipat ako from Philippines and australia, same goes to other region kung gusto mo lumipat ng region get the 3 impt part COUNTRY, STATE, ZIP Code then thats it pansit..
