We all know that the Samsung Galaxy Nexus is coming to Sprint, but there’s been much speculation of exactly when. Leading the pack of rumors is the date of April 22nd. In addition, some recent photos sent to Phandroid may have possibly cemented this suspected release date. An anonymous tipster shared what appears to be retail marketing posters for the Galaxy Nexus. While the posters don’t display anything new, its packaging tells a different tale. Clearly labeled for a marketing launch of April 15th, it makes sense that Sprint would put up marketing materials one week prior to the launch of a new device. As the Now Network prepares to begin accepting pre-orders for the LG Viper, it’s looking more likely that Sprint will finally be taking the plunge into LTE before the month of April comes to an end.
