Just in case it wasn't already clear that Samsung is prepping a next-generation Windows Phone for Verizon, the company has just passed the device (the SM-W750V) through the FCC. The approval confirms the presence of Big Red-friendly LTE and CDMA frequencies, as well as GSM and HSPA for world roaming. The handset is also large enough to hold that rumored 5-inch screen. The filing doesn't offer any clues as to when the hardware ships, but we wouldn't rule out the possibility of an announcement at or around Mobile World Congress.
