Could there be a sliver of truth to the Facebook phone rumors? While Facebook has already denied that it’s working on its own phone, word is now going around that the social networking giant is working with mobile phone maker INQ Mobile to come up with two smartphones that will highlight Facebook's core features. If the rumor is true, the devices will have a network tie-up with AT&T and are expected to be released in Europe in the first half of 2011 and hit the US in the 2nd half. INQ is no stranger to social networking as the company has previously unveiled its INQ1, a phone billed as a social networking phone and had tight integration with Facebook, Skype, Yahoo, Google, eBay, and Windows Messenger. What do you think? Could this be the Facebook phone?
