On October 7, 2009, Amazon announced an international version of the Kindle 2 with the ability to download e-books wirelessly. This version released in over 100 countries. It became available on October 19, 2009. The international Kindle 2 is physically the same as the U.S.-only Kindle 2, although it uses a different mobile network standard.
The original Kindle 2 used CDMA2000 for use on the Sprint network. The international version used standard GSM and 3G GSM, enabling it to be used on AT&T's U.S. mobile network and internationally in 100 other countries with Amazon offering free unlimited roaming.
