This weekend saw an update of that alleged Sprint inventory sheet featuring unannounced devices and their corresponding release dates, and we’ve learned that the SPH-D600 on that list will launch as the Samsung Conquer 4G.

A Gingerbread QWERTY slider powered by a single-core 1GHz processor, Conquer 4G has been likened to a low-end Epic 4G: while it shares that model’s WiMax capabilities and front-facing camera, it offers just an HVGA (320×480) resolution and 3.1-megapixel primary shooter.

July 24th has been listed as the planned consumer launch, probably at a price point between $50 and $100.
