Sprint's finally starting to get the ball rolling with its first LTE devices, announcing this morning that it's ready to begin pre-orders of the LG Viper 4G on April 12, and the next-gen goodness can be yours for $100 (after $50 mail-in rebate). The actual release date wasn't specified, but at least we know this means it's coming up much sooner rather than later. As a refresher, the Viper comes with Gingerbread, a 4-inch WVGA NOVA display, a 1.2GHz dual-core Qualcomm MSM8660 Snapdragon S3, 1GB of RAM, NFC and Google Wallet functionality, a microSD slot, 50GB cloud storage from Box and a smattering of eco-friendly features.
