There's some potentially bad news for Nokia users who were willing to dabble in untamed firmware releases via the company's online repository. Navifirm, which has inadvertently offered several early glimpses of updates for Nokia hardware, will shutter open access to its firmware repository at the end of the month. Starting in February, the system will require a "Nokia Online" login for access to both application and device software downloads. The brief announcement doesn't detail whether this would involve a standard Nokia account or something else, but it might mean fewer previews --
