Sprint's just given us the heads up that the LG Viper 4G LTE, with its 4-inch NOVA display, Android 2.3 Gingerbread, 1.2 GHz dual-core processor, 5MP camera and NFC radio (along with Google Wallet) will be up for pre-order starting April 12. The Viper, which we got a dark look at back at CES in January, admittedly won't set any hardware records. But the price is right -- $99 on contract, with $50 mail-in rebate. Sweetening the deal is 50GB of cloud storage from Box. Sprint says full availability dates will be announced later this month.
