== Commercial Aspects of GSM vs CDMA? ==
I came to Wikipedia wanting a brief, introductory overview of why my Sprint CDMA phone can't be used in many places overseas (unless it has a GSM "on the side" built in, like in the Blackberry 9630 or the iPhone 4S phones). I want to know why some countries chose GSM and others chose CDMA or mixed. Why does the US have so much more CDMA than the rest of world? I want to know why some carriers use CDMA and others use GSM. (I'm curious what it means to 'unlock' a GSM phone, and if the same thing can be done with dual-system phones like the iPhone 4s or Blackberry 9630 Tour.) In short, I really don't care '''at all''' about the underlying physics or electrical engineering. I'm interested in the business, commercial, user, and political (standard-setting) side of things. Perhaps there are articles on this, but they are not clearly linked, if so. Or perhaps they don't exist?
