The guys over at S4Gru.com say they have Sprint sources that confirm the release of the Sprint Galaxy Nexus to be on April 15th, which is a Sunday. Sources are reporting that it's unlikely the device would actually be released on a Sunday, but it's more likely that we'll see a Friday (the 13th) or Saturday launch. It's also worth noting that rumors are pointing to the Galaxy Nexus launching on Sprint with LTE initially turned off. The devices will have LTE radios, but they'll boot into 3G when they're activated. Users will then be able to switch from LTE to 3G, and of course to WiFi. Many are saying that this is because Sprint's LTE network is still in its infancy, and might not be strong enough to handle mass amounts of Galaxy Nexii connecting to it at once.
