Unlocked versions of the iPhone 3GS are now on sale from Apple's Hong Kong online store. In contrast with many regions, including a number with multiple iPhone carriers, Hong Kong only requires that shoppers have the proper SIM card inserted to use a 3GS with any GSM network. 16GB phones are being sold online for $5,388 HK ($692 US), while 32GB models cost $6,288 HK ($808 US).
