First it was AT&T unceremoniously launching the launching the HTC Pure with Windows Mobile 6.5 two days before Microsoft officially unleashes the new OS, and now it looks like someone's flipped the switch on the Windows Marketplace for Mobile a day early. Engadget Mobile has noted that the Marketplace is live for Pure users, though we're also getting word that it's not working so well for those using cooked ROMs, and that there are only several dozen apps available right now (or, roughly the same amount as in Palm's App Catalog - zing!), though we're certainly expecting that to change in just a few hours.
