Unlocked iPhone 4S only works on GSM networks (T-Mobile)

We have learned an interesting fact about the unlocked iPhone 4S that will be coming out in November.

You will not be able to take your unlocked iPhone 4S over to Sprint or Verizon to enable their services. It seems that you will only be able to take your unlocked iPhone 4S over to GSM Networks (ie. T-Mobile), but you should expect to be able to only use the EDGE 2G speeds. Having an unlocked iPhone 4S means that you can swap the SIMs when you travel internationally, which could be very helpful if you dont want to spend a load of money on phone calls. Quoted:

“The unlocked iPhone includes all the features of iPhone but without a contract commitment. You can activate and use it on the supported GSM wireless network of your choice, such as AT&T in the United States.* The unlocked iPhone 4 or iPhone 4S will not work with CDMA-based carriers such as Verizon Wireless or Sprint. If you don’t want a multiyear service contract or if you prefer to use a local carrier when traveling abroad, the unlocked iPhone 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. To start using it, simply insert the micro-SIM card into the slot on your iPhone and turn it on by pressing and holding the On/Off button for a few seconds. Then follow the onscreen instructions to set up your iPhone.”

So you will need to think which is more beneficial to you the contract deals or just having the unlocked phone. Either way you will still have an iPhone 4S and that’s all you’ll care about.
