Florida-based BLU Products might be more known for its budget Android smartphones, but it does have a few Windows Phones on its shelves. One of those, the BLU Win HD, silently got a much needed upgrade. Appearing at Microsoft's Store, the Win HD LTE brings more than just new LTE connectivity. It also bears a more powerful processor but still with a lovable budget price tag. And though it only runs Windows Phone 8.1, it comes with the promise of Windows 10 once the latter starts rolling out.
