Verizon has officially launched the Samsung 4G LTE Smartphone introduced at CES as the Samsung Droid Charge, giving it an April 28th release date and hefty $300-on-contract price. Verizon’s other LTE-capable handset, the HTC Thunderbolt, retails for a subsidized $250.

As rumored, the 4.3-inch Charge will offer class-leading hotspot capabilities with its ability to connect to up to 10 devices simultaneously; hotspot functionality will be offered free for an unspecified introductory period.

Powered by a 1GHz processor, the Froyo-equipped Droid Charge packs an eight-megapixel rear camera along with 1.3-megapixel front-facing cam. Charge will like be joined shortly by a variant of the Galaxy S II, although that device will feature a dual-core processor but not 4G data.
