I would imagine from this news that Barablu is using dual mode phones to allow people to have free WiFi telephony calls within its network. This is exactly the kind of news that is great for consumers but probably gets wireless service providers furious. The last thing they want is to take minutes off their network. Of course if customers scream for dual mode some providers will cave. Others may not. I point to Verizon Wireless and their lack of full bluetooth support as a company that probably will be last to the dual mode party.
