Official Apple Store上买的iPhone 4S - Unlocked(GSM) - 16GB $649.00是不是移动、联通、电信三网都能用的

按照官网的说法，unlocked的4s只支持GSM网络，也就是现在咱们普通的2G移动网络。不支持电信的cdma。The unlocked iPhone works only on supported GSM networks, such as AT&T in the U.S. When you travel internationally, you can also use a micro-SIM card from a local GSM carrier. The unlocked iPhone will not work with CDMA carriers such as Verizon Wireless or Sprint.简单翻译就是解锁的iphone只支持GSM网络，如果你去其他国家，可以使用当地的GSM运营商提供的小卡。解锁的iphone不支持CDMA
