A lot of people have been anticipating a Bluetooth phone from Verizon, only to be disappointed by lack of OBEX. Verizon says they have no plan to add OBEX because it doesn't fit their business model--greedy bastards. PC Magazine doesn't have very nice things to say either. More discussion here."
Here's another site on the v710 crippling that Verizon has done to this phone. And this crippling prevents it from sharing phone books. http://www.nuclearelephant.com/papers/v710hackers.html
