Facebook has scheduled to hold a media event on Tuesday, reawakening rumors that the social netowrk will launch its own phone.

The event, set to be held at Facebook's headquarters on January 15, is prompting - for one more time - speculations that a Facebook smartphone is on the works.

Last November reports surfaced that HTC had been working with Facebook to develop a phone, code-named the Opera UL. However, the phone never materialized Facebook's CEO Mark Zuckerberg had denied the rumors.

TechCrunch is now claiming that the launch of a phone is imminent, indicating that "multiple sources have told us that they expect some sort of Facebook Phone to be on display on Tuesday."
