Verizon prepping to buy back some of VzW from Vodaphone?

Some are speculating that Verizon is sick of sharing its wireless bed with Vodaphone and is looking to buy out more of Vodaphone's stake in VzW.  The speculation is fueled by Verizon's June 14th SEC filing in which they asked for another $8 billion in debt, which raised many an analyst eyebrow.  No one is saying Verizon will purchase the entire 45% stake Vodaphone owns in the carrier, but speculation continues that they'll buy some part of the stake.

Verizon spun off the wireless unit way back in 2000 and took $10 billion for Vodaphone's minority stake in the company, but with all the success of Verizon as a wireless carrier, it'd likely take more than $10 billion to buy it back.
