HTC has announced that it will begin selling the S743 – a U.S.-specific variant of the European S740 – sometime this quarter (read February or March).  The S743 is a non-touchscreen Windows Mobile 6.1 Standard handset with a 2.4-inch QVGA display and 850MHz/1900MHz HSDPA.

HTC is currently planning on selling the S743 through U.S. electronics retailers like BestBuy and Amazon rather than offering the smartphone via wireless carriers.  This may or may not change, but if that’s the case expect to pay a bit more without the carrier subsidy.
