Wondering just how well a tablet would do if picked up and marketed by all four major carriers in America? We're still waiting for the breakdown within our borders, but there's hardly a doubt that the unprecedented carrier arrangement has helped Samsung shatter its estimates on Galaxy Tab sales. Purportedly, the outfit has just passed the one million mark in global sales of the 7-inch Android tablet, but Information Week is quick to point out that Sammy's not clear on whether that's units in the sales channel or units in the hands of consumers. Either way, one million's nothing to scoff at, particularly when you consider that only 600,000 had been sold as of November 22nd. The firm's now hoping to move 1.5 million of 'em by the year's end, and while that's still well short of the estimated seven million iPads that have been sold to date, it's a sales rate that we're sure no one at Samsung is kvetching about.

Update: CNET heard from a Samsung representative that the company hasn't officially announced the sales figure here, but hopefully we'll get some clarification soon. It's possible that the PR team simply isn't ready to dish out the number in official fashion yet. We'll keep you posted.

Update II: So, it's just what we expected -- the numbers are real, but Samsung wasn't quite ready to come clean with 'em. According to Kim Titus, Director of Public Relations for Samsung Mobile, the company has "sold one million Galaxy Tabs globally." Good on 'em!
