Many stores are offering unlocked handsets, dependant on Apple’s relationship with carriers in the country. Unlike in the U.S and Japan, Apple has made the iPhone 4S available unlocked in many regions, helping users easily upgrade from their iPhone 4 handset.

The iPhone 4S will go on general sale the 22 additional countries in one week’s time. Apple will then focus on making the handset available in more than 70 countries by the end of the year.
