It looks like AT&T may soon have another Windows Phone device coming available. The details are coming by way of a recent FCC filing and a recently leaked AT&T device roadmap. According to the FCC filing, a smartphone bearing the model number of PI86100 has been spotted and is showing support for the AT&T 4G LTE network. And now moving over to the leaked roadmap, that was showing the HTC Titan II smartphone with that same model number. Further details from that roadmap show that the Titan II will be available on March 18th and cost $200 on a two-year contract. Bottom line here, this FCC filing did not reveal all that much new, however it did match up some of those pieces and if nothing else, it is nice to see that an FCC issue will not be responsible for any delays come March.
