Continuing its barrage of new device announcements at Mobile World Congress, ZTE just announced its second Windows Phone handset — the Orbit is a low-end device that's set to take advantage of the latest version of Windows Phone 7.5. We don't have details on what's under the hood just yet, or even how large the screen is, but with 4GB of internal memory and a 5-megapixel camera it's clear what section of the market the company is targeting. ZTE's MWC press conference is happening right now, and we'll be sure to let you know if we hear any more details about the Orbit from within.
