Agreed on all fronts.

Apple’s Iphone is one of the most sought-after gadgets in the world today. It has the most excellent features that can mesmerize anybody – which just proves that its popularity will not be waning out any time soon. Iphones, by default, are usually SIM-locked to just one network – which limits you to the services which that particular network offers and nothing else. Hence, you will not be able to avail of the better services that another network offers, or the more affordable fees that the competing network has. Fortunately, this dilemma can be easily solved by unlocking your Iphone. By doing this, you will have a wider choice of apps for your Iphone and you will be able to avail of better services that your current network provider might not be able to provide. Thanks a lot.

So, the big deal here is CDMA+GSM on the iPhone 4S, but I do not understand the implications.

1) I see different issues in the GSM vs CDMA iPhone 4s. They have different firmware, and we have different issues in our apps running on them. The iPhone 4S solves this issue.

2) When I have CDMA + GSM iPhone, how does it work with carriers? Are there two sim cards? Can I sign up for AT+T and Verizon? Can I switch to Sprint?

@Stephen, this article speaks well to the topic:

Why the iPhone 5 Never Arrived (http://bit.ly/qlv2em), and it basically argues that the same Qualcomm chipset (MDM6600) can accommodate both CDMA+GSM, with the implications being that Apple either creates different firmware for each phone or has a universal build that toggles on for the appropriate carrier.

My guess is the former because I believe that the carriers prefer a separate sim card + firmware combo to hardware bound to their network.

That stated, it's unclear that 4S will actually support the ability to switch networks for the above reasons. If you parse the messaging on Apple's site about world phone, the way I read it is that you can buy a phone that will run on either CDMA or GSM but you can only roam on GSM.
