Fazal Majid wrote to me about Bluetooth phones for CDMA networks (like those run by Sprint and Verizon). He pointed me to this article from The Register which discusses Qualcomm's monopoly over CDMA technology. The article cites that as the reason no Bluetooth CDMA phones are available. The article says:
Consumers will not make their choice of network operator based on the underlying network technology. Their choices are influenced heavily by the the appeal, popularity and price of handsets and services.
This is so true. I've been a Sprint customer since for 5 or 6 years, but I'll switch for a Bluetooth phone. Not to mention the fact, that I'm quite disappointed with Sprint's latest offerings. The data and voice service are great, but what's wrapped around the base technology is underwhelming.
