Sharp FX Plus for AT&T quietly goes on sale at Walmart

After playing peek-a-boo on a Walmart brochure last week, the Sharp FX Plus just became a bona fide reality. Featured as an exclusive to the retain chain, the Sidekick-emulating Android handset has its own piece of real estate on its online store. The AT&T phone's offered for free with a two-year contract ($350 without the commitment), though it's currently backordered. We're not seeing anything new on the spec sheet: it comes preloaded with Android 2.2, has a 3.2-inch display, and holds a grand total of 512MB internal memory (expandable to 32GB via microSD). Throwing a three megapixel camera into the mix doesn't earn any wows, either, but to be fair, it's meant to be a respectable yet inexpensive option for messaging fanatics. And it has a plus at the end of its name -- that's gotta count for something, right?
