LG Viper available for preorder today for $99, officially in stores April 22

As promised, the Sprint LG Viper 4G LTE is available for preorder today for $99. (That's on a two-year contract and after a $50 mail-in rebate.) In exchange for that Benjamin you'll get a 4-inch NOVA display, Android 2.3 Gingerbread, a dual-core 1.2GHz processor, 5MP camera, NFC radio and Sprint ID, plus eventual 4G LTE data on Sprint's fledgling 4G LTE network. Plus, you'll get 50GB of online storage from Box.

Sprint's website says it'll "do our best to get it to you before Sunday, April 22," which suggests that'll be the official in-store date. So, who's in?

Update: Sprint's just made it official, saying it'll definitely be in stores on Sunday, and that preorders may arrive as early as April 20.
