Samsung Galaxy Nexus is certainly the star of Sprint’s upcoming LTE device lineup for now, but a second 4G LTE smartphone was announced this week at the Consumer Electronics show that will offer early LTE adopters on Sprint’s network as solid second choice. Featuring a 4-inch display, a dual-core 1.2GHz processor and  Google Wallet support thanks to an NFC chip, the LG Viper 4G LTE is a well-equipped Android smartphone that will launch later this half of the year. It will have Android 2.3 Gingerbread at launch, but Sprint has promised an upgrade to Ice Cream Sandwich shortly after the device is released.
