Sprint announced Thursday morning that the LG Viper will be available on April 22nd, but now there’s further proof that it might not launch alone. According to a screenshot obtained by BGR, Sprint also has plans to launch the Galaxy Nexus on the 22nd. We’ve already heard this rumor before; a leaked document several weeks back suggested that Sam’s Club would begin selling the device on April 22nd, too. Sprint hasn’t given official word yet, but we wouldn’t be surprised if two 4G LET devices launched on the same day. After all, choice is always good for the consumer and Sprint no doubt wants to push its budding network as much as possible.
