HTC has not found tremendous success thus far with its first two tablet offerings. Despite a carrier deal with Sprint, the Sense UI, a unique note-taking feature called Scribe and a bunch of scantily-clad women toting the tablet at a few events, our sources suggest HTC Flyer sales have not been stellar. The company’s second tablet offering, the Jetstream, was priced out of contention here in the U.S., running $700 with a two-year data contract from AT&T. According to a recent report, HTC’s lucky number three will be unveiled in February at the annual Mobile World Congress show in Barcelona, Spain. Details are limited for the time being, but DigiTimes cites a report from Chinese-language Commercial Times in stating that a quad-core Tegra 3 tablet from HTC will be unveiled at the show and will launch some time before the end of the third quarter. Also likely due from the Taiwan-based vendor at MWC are the quad-core HTC Edge and the dual-core HTC Ville smartphones BGR exclusively detailed last week.
