MyPhone beta page that popped up on getskybox.com yesterday? It's back up now and being hosted under the company's official domain, with everything apparently intact except that tantalizing "Sign In" button. According to a statement from the gang at Redmond, a limited invite-only beta is in the cards, and more details on the syncing service formerly known as SkyBox are coming to Mobile World Congress later this month. As for the beta itself, the wording's a bit ambiguous here -- will we just be getting new details on the trial or will the signup actually launch then? Looks like we'll find out for sure in just over a week.
