There's no question that Verizon's making a big push for LTE, but it appears that Microsoft has yet to take notice -- after all, Android continues to dominate Big Red's 4G network, with nary a Windows Phone in sight. VZW hopes that'll change, however, with CMO Marni Walden revealing that the company has "communicated to Microsoft that LTE is critical to us," suggesting that the ball is in Windows Phone's court. Meanwhile, Microsoft smartphone chief Andy Lees had previously confirmed that LTE functionality was on the Windows Phone roadmap, saying back in October that the company and its partners were looking at how 4G LTE support could be integrated. To date, Lees has declined to give any indication as to the actual timing for the first LTE models. In other news, Verizon has offered Microsoft a custom-made promise ring just to make sure its intentions were understood.
