Still rockin' Windows Mobile 6.x? Time to check all your apps for updates one last time. Microsoft has issued a final reminder that, beginning today, the Marketplace for 6.x devices will no longer be available. This means you won't be able to browse, buy or download apps from your phone via the service. Everything you already have will, of course, work just fine, but if you needed to reinstall something -- now is the time to do it. Unless it's available direct from third party sites, in which case you'll have a little breathing space. Still, better safe than sorry.
