Much as it has been doing in Canada for some time, Apple is now offering unlocked versions of its iPhone 4 in the US. Both 16GB and 32GB versions are available in black or white.
If you don’t want a multiyear service contract or if you prefer to use a local carrier when traveling abroad, the unlocked iPhone 4 is the best choice. It arrives without a micro-SIM card, so you’ll need an active micro-SIM card from any supported GSM carrier worldwide.
Despite being unlocked, the Apple iPhone 4 will only work on the AT&T network in the US (an unlocked CDMA version is not available).
The unlocked 16GB iPhone 4 sells for US$649 while the 32GB version is available for US$749.
