My Iphone 4S is considered a world phone, I travel to Singapore a lot. I was able to have Verizon unlock my 4S and use a prepaid Singtel microsim. Trying to read the 3 versions, it appears that the Iphone 5 will work based on this statement. The new iPhone 5 now comes in three LTE versions, all of which continue to support the global GSM/UMTS services of iPhone 4S (Quad Band 2G GSM/EDGE on 850, 900, 1800, 1900 MHz, and Quad Band 3G UMTS/HSDPA/HSUPA on 850, 900, 1900, 2100 MHz) with new support for "4G" DC-HSDPA (which at up to 42Mbps is as fast as most carriers' 4G LTE service). Only one of the three versions continues to support CDMA. Anyone care to agree?
