Facebook Phone?

Facebook today announced a press event on the 15th of Jan 2013.

Facebook gave no clues as to what it plans to announce; the invite only read, “Come and see what we’re building.”
It has been widely reported that Facebook have been working on a phone to rival the iPhone.
This is the first media gathering the company has hosted since it announced a number of new retail partners for its Gifts app at FAO Schwartz in New York City in November.
