Though Verizon Wireless and corporate half-parent Vodafone are finally getting close to achieving technological synergy now that both are moving to LTE for their next-gen networks -- and contrary to recent statements -- rhetoric is heating up that suggests the marriage may not last forever. Speaking at an investor's get-together this week, Voda CEO Vittorio Colao said that "the board continues to look at" the company's investment in the joint venture with Verizon -- which we take as executive-speak for "everything's for sale for the right price." The popular rumor is that Vodafone's bummed about Verizon's failure to pay dividends for the past four years, which effectively means that Big Red isn't actively contributing to the wireless giant's bottom line. Verizon's made no secret of the fact that it'd love to own the joint venture outright, so come on, guys... Verizon's got money, Voda's got the goods, let's sit down at that oaken conference table on the 45th floor and work this out.
