I finally switched over from GSM to Verizon a few months back because of the Motorola V710 bluetooth enabled phone Verizon touted in its ads. Verizon has the best network bar none and they often take advantage of their network superiority by locking customers into longer-term contracts and now intentionally disabling features on their phone. I wrote about Verizon disabling bluetooth features on the V710 in October of 2004.
Generally I have been unhappy with the bluetooth capabilities of the phone as not only can I not sync with a PC to download address books or photos, etc, I also have problems connecting the phone with a few of my bluetooth headsets. I have searched the web and haven't seen anyone duplicate these problems. Basically, the headset and phone don't work well together, meaning a call can't be answered in the headset but must be manually transferred every time. SonyEricsson bluetooth integration is an order of magnitude better and I am not sure whether Verizon, Motorola or both are to blame. I got to thinking about this when I discovered some California residents are suing Verizon over the intentional disabling f bluetooth features.
Verizon's defense is likely that they own the network and subsidize the cost of the phone so they should be able to disable whatever they want. They have a point. Car companies often disable engine performance in some cars and sell them as entry-level vehicles. Why can't Verizon do the same? The best solution is to allow a high-end version of the phone for more money that has all the bluetooth functions you could ask for. That would solve the problem and keep Verizon from getting trashed on message boards all over the web.
